Pro-Cotton Handmade - 3 Pack By Coil Master

Thirty strips of 100% Indonesian organic cotton, split across three packs of ten. That is what Coil Master's Pro-Cotton gives you: unbleached, untreated wicking material built specifically for rebuildable vape atomisers. No whitener, no colourant, no chemical processing at any stage. 

The cotton is handmade in Indonesia and cut into uniform strips sized to fit standard coil inner diameters without trimming or tearing. If you build your own coils on an RDA, RTA, or RDTA, this is the wicking step sorted. Pair it with your preferred Vape Coils and the flavour difference over generic cotton is noticeable from the first pull.

Why vapers choose this:

• Zero chemical treatment from start to finish. No bleach, no whitener, no colourant. The cotton touches nothing except your e-liquid and the coil it sits inside, which means cleaner flavour from the very first draw.

• Pre-cut strips eliminate guesswork. Each strip is sized to wick standard coil builds without needing scissors or eyeballing thickness, so you get consistent results every rewick.

• Minimal break-in taste. Most cotton wicking needs three or four tanks before the cottony flavour fades. Coil Master's organic processing cuts that break-in period noticeably shorter.

• Thirty strips across three packs means weeks of rewicking before you run out, even if you build daily.

• Handmade in Indonesia from organic cotton. Not mass-produced synthetic padding repackaged for vaping.

Pro-Cotton Handmade Features

Why Organic Cotton Changes the Flavour

Standard cotton pads from a pharmacy shelf go through bleaching and chemical softening. Those processes leave trace residues that your coil heats up, and you taste. Coil Master's organic Indonesian cotton skips all of that. 

The fibres are naturally absorbent without needing chemical treatment to improve saturation, and the flavour profile of your e-liquid comes through without the background noise. Fair enough, the difference is subtle on heavy dessert juices. On clean fruit and menthol profiles, though? Not even close.

Pre-Cut Strips Save Time and Cotton

Bulk cotton pads need cutting, peeling, and shaping before they fit inside a coil. You waste material every time. The Pro-Cotton strips are already sized for standard 3mm and 3.5mm inner diameter coils, which covers the majority of RDA and RTA builds. Pull a strip, roll the leading edge, thread, trim, tuck, juice. The whole rewick takes under two minutes once you have done it a few times.

Chain Vaping Without Dry Hits

The fibre density in this cotton holds liquid well. Coil Master specifically designed it for sustained chain vaping with minimal dry hit risk, because the cotton feeds e-liquid back to the coil surface faster than loosely packed alternatives. If you take long sessions at higher wattages on a DTL Tank or dripper, that wicking speed matters.

Stronger Throat Hit, Cleaner Delivery

One detail that gets overlooked: the purity of the cotton affects nicotine delivery. Without chemical residues dulling the throat sensation, the nicotine throat hit comes through sharper and more defined. Practically speaking? Your 3mg freebase feels like 3mg, not like a muted version of it.

Three Packs, One Purchase

Each individual pack holds ten strips. You get three packs per order, and each pack reseals to keep the unused strips clean. Storing them in the original packaging rather than loose in a drawer keeps dust and lint away from the fibres, which matters more than most people think when you are heating cotton to 200°C.

How to Wick With Pro-Cotton Handmade

1. Remove your old wicking. Pull the spent cotton from your coil using tweezers or your fingers. Dry-burn the coil briefly at low wattage to clear residue, then let it cool completely.

2. Take a single strip from the pack. Roll one end between your fingertips into a narrow point, tight enough to slide through the coil's inner diameter without forcing it.

3. Thread the cotton through the coil until equal lengths hang from each side. The cotton should move through with slight resistance. If it slides freely, it is too thin. If the coil shifts when you pull, it is too thick.

4. Trim both tails to just long enough to reach the juice wells or deck channels on your atomiser. Tuck them down gently without packing them tight.

5. Saturate the cotton thoroughly with e-liquid. Apply drops directly onto the cotton inside the coil and along both tails until the fibres darken and stop absorbing. Wait three full minutes before firing. This cotton absorbs quickly, but giving it that extra time ensures the innermost fibres are fully wet.

6. Start at low wattage and take two or three short draws. Increase to your preferred power once the flavour comes through clean.

What's in the Pro-Cotton Handmade Box

Three individually wrapped packs, ten cotton strips per pack. Thirty strips total. No tools, no coils, no e-liquid included. You supply the build and the juice. If you need coils or wire, the Vape Accessories section has what you need to complete the setup.

Built for Every Rebuildable Atomiser

The Pro-Cotton strips work with any rebuildable atomiser that uses cotton wicking. That covers single-coil RDAs, dual-coil RDAs, RTAs with top or bottom airflow, and mesh-deck RTAs or RDTAs. The strip width suits 3mm to 3.5mm coil inner diameters out of the pack. For larger builds at 4mm or above, you can layer two strips or gently stretch a single strip to fill the space.

What it does not suit: pre-built pod coils, press-fit coil heads, or any sealed coil system where you cannot access the wicking channel. Those use factory-installed cotton and are not user-serviceable. If you are running a Vape Mod with a rebuildable deck, though, this cotton fits.

About Coil Master

Coil Master built its name on DIY vaping tools. The brand's coiling kits, ohm readers, and ceramic tweezers became standard gear for anyone building their own coils, and the 521 Tab remains one of the most recognised coil-testing devices in the hobby. 

Pro-Cotton is the wicking side of that same toolkit. Coil Master sources the cotton directly from Indonesian growers and processes it without bleach or chemical treatment, keeping the production chain short and the end product clean. For vapers who build, Coil Master is one of those brands that just keeps showing up in the kit bag.

Stock Up and Save

Thirty strips sounds like a lot until you are rewicking twice a week. At that pace, a three-pack lasts roughly a month. Grab two, and you are covered through the summer without thinking about it.

Every order from Pirate Vapes ships the same day before 4 pm in padded packaging, so the cotton arrives sealed and clean. Age-verified checkout, over 18s only. All products are TPD compliant. Spend over £25 and delivery is free with Free Pirate Post.

Conclusion

The Pro-Cotton Handmade by Coil Master is a straightforward product that does one thing well: clean, chemical-free wicking for rebuildable atomisers. Thirty organic cotton strips across three packs, handmade in Indonesia, with no bleach and no additives.

If you build your own coils and care about flavour purity, this cotton earns its place in the rotation. Browse more Drip Tips and Mouthpieces or the full Vape Tanks range at Pirate Vapes.

FAQs

How many strips come in the Pro-Cotton 3 pack?

Thirty. Ten strips per pack, three packs per order. Each strip is pre-cut and ready to thread.

Does the cotton need breaking in?

Less than most. A few draws at low wattage clear any initial cotton taste. It is noticeably faster to break in than unprocessed cotton pads from a chemist.

What coil diameter does the Pro-Cotton fit?

Standard 3mm and 3.5mm inner diameters work straight from the pack. For 4mm builds, gently stretch the strip or layer two thinner pieces to fill the coil properly.

Can I use this in a pod kit or pre-built coil head?

No. Pro-Cotton is designed for rebuildable atomisers only: RDAs, RTAs, and RDTAs where you install and wick the coil yourself. Pre-built coil heads are sealed and cannot be rewicked.

How often should I change the cotton?

Every three to seven days with regular use. When the flavour dulls, the vapour thins out, or the cotton looks dark and gunked, it is time to rewick. Sweeter liquids shorten the lifespan.

Is Coil Master Pro-Cotton bleached?

No. Zero bleach, zero whitener, zero chemical treatment. The cotton is unprocessed organic fibre, handmade in Indonesia.
