Description - Mechlyfe Grenade Cotton Bio 100% Pure
The Fallout x Mechlyfe Grenade Cotton Bio is premium 100% pure organic vape cotton made in the USA for rebuildable coils. Supplied as convenient pre-cut cotton laces, it is available in 2.5mm, 3.0mm and 3.5mm sizes so you can choose the right fit for the internal diameter of your coil.
Each pack contains 20 pharmaceutical-grade organic cotton laces, making Grenade Cotton an easy option for rewicking compatible RDAs, RTAs and other rebuildable atomisers. The pre-sized format removes much of the guesswork involved with separating loose cotton and makes it easier to achieve a consistent amount of cotton through your coil.

Grenade Cotton Bio Size Options
Fallout x Mechlyfe Grenade Cotton Bio is available in three different diameters. Each pack contains 20 laces of your selected size.
2.5mm Grenade Cotton
Designed for rebuildable coils with an internal diameter of approximately 2.5mm. Choose this option for smaller coil builds where a narrower cotton wick is required.
3.0mm Grenade Cotton
A versatile option for rebuildable coils with an internal diameter of approximately 3.0mm and a useful choice for many everyday RDA and RTA builds.
3.5mm Grenade Cotton
The larger option in the range, designed for rebuildable coils with an internal diameter of approximately 3.5mm where a thicker cotton wick is needed.
How to Choose Your Grenade Cotton Size
Choose the cotton size that matches the internal diameter of your installed coil. For example, a 3.0mm internal-diameter coil should normally be paired with the 3.0mm Grenade Cotton option.
The cotton should pass through the coil with light resistance without being excessively tight. Too much cotton can restrict e-liquid flow, while too little cotton may not make sufficient contact with the inside of the coil.
How to Use Fallout x Mechlyfe Grenade Cotton
- Install and prepare your rebuildable coil.
- Select the Grenade Cotton size that matches your coil's internal diameter.
- Feed one cotton lace carefully through the centre of the coil.
- Position the cotton so an even amount extends from each side.
- Trim the ends to suit the wicking channels or build deck of your atomiser.
- Gently position the cotton into the required wicking areas.
- Fully saturate the cotton with e-liquid before vaping.
If you are new to rebuildable atomisers, see our guides on how to use an RTA and how to use an RDA for more information on building and wicking.
What Is Fallout x Mechlyfe Grenade Cotton Compatible With?
Grenade Cotton Bio is intended for rebuildable vape atomisers where the user installs and wicks their own coils, including compatible RTAs and RDAs.
The correct option depends on the internal diameter of your build:
- 2.5mm: for approximately 2.5mm ID coils
- 3.0mm: for approximately 3.0mm ID coils
- 3.5mm: for approximately 3.5mm ID coils
This cotton is not a replacement coil and is not designed to replace sealed cotton or built-in coils found inside standard replacement vape pods or push-fit stock coils.
Why Use Pre-Cut Vape Cotton Laces?
Pre-cut cotton laces make rewicking quicker by providing a consistent amount of cotton in a predetermined diameter. Rather than pulling apart and measuring loose cotton for every build, you can select the size that corresponds with your coil and feed the lace directly through it.
This makes Grenade Cotton particularly useful for rebuildable users who regularly use the same coil diameter and want a straightforward, repeatable wicking setup.
What's in the Pack?
- 20 x Fallout x Mechlyfe Grenade Cotton Bio laces
Please note: Each pack contains one selected size only. Choose between 2.5mm, 3.0mm or 3.5mm before adding the product to your basket.
