Vapefly Firebolt M Cotton | 6mm Mesh Cotton Wicks

Vapefly Firebolt M Cotton for Mesh Builds

Vapefly Firebolt M Cotton is premium pre-cut organic Japanese cotton developed specifically for mesh rebuildable atomisers. Each strip is ready to use and features an agleted tip that makes threading cotton beneath a mesh strip faster, cleaner and easier than preparing loose cotton by hand.

Firebolt M is the wider 6mm mesh version of Vapefly's popular Firebolt Cotton. Each cotton strip is approximately 60mm long, giving builders enough material to position, trim and tuck the wick correctly inside compatible rebuildable atomisers.

Made from 100% organic Japanese cotton, Firebolt M is designed for fast e-liquid absorption, reliable wicking and clean flavour delivery. It is suitable for mesh RTAs, RDAs and RDTAs and has also been specifically listed for use with the Vapefly Siegfried Mesh RTA / Siegfried Kit.

Why Choose Firebolt M Cotton?

Mesh coils require a larger and more evenly distributed amount of cotton than traditional round-wire coils. Firebolt M Cotton is designed specifically for these wider mesh builds, helping remove the guesswork involved in measuring and shaping loose cotton.

The agleted end works similarly to a shoelace tip. Feed the tip through or underneath the mesh build, pull the cotton into position and then remove the tip before trimming and arranging the wick. This makes Firebolt M particularly useful for rebuildable users who want a faster and more consistent mesh-wicking process.

Firebolt M vs Standard Firebolt Cotton

Firebolt M is designed for mesh builds, commonly listed as 6mm, and comes in a wider format suited to mesh coil decks.

Standard Firebolt Cotton is designed primarily for conventional round-wire coil builds and is available in narrower coil-ID sizes (2.5mm, 3.0mm and 3.5mm).

If you are building a mesh RTA, mesh RDA or mesh RDTA, Firebolt M is the version you want.

How to Use Vapefly Firebolt M Cotton

Carefully loosen or lift the mesh according to your atomiser's building instructions. Guide the agleted end of the Firebolt M Cotton underneath the mesh and gently pull the cotton into position.

Make sure the mesh makes even contact with the cotton without crushing it excessively. Trim away the agleted end and any excess cotton, then position or tuck the wick tails according to your atomiser. Thoroughly saturate the cotton with e-liquid before firing the build.

Important: Mesh must maintain proper contact with the cotton. Insufficient wick contact can create hot spots or dry areas.

Compatible Builds

Firebolt M Cotton is intended for rebuildable mesh atomisers, including compatible mesh RTAs, mesh RDAs, mesh RDTAs, mesh rebuildable decks and the Vapefly Siegfried Mesh RTA / Siegfried Kit. Compatibility ultimately depends on the dimensions and design of your individual rebuildable deck.
