No, all Penjamin Pockets are all made from 100% breathable cotton. You can easily hit your pen while in the pocket without resistance. Multi-layered options, such as the bass fish, may slightly decrease airflow but not so much where it might burn out your cartridge. For the multi-layered options it is best to have a battery that allows for airflow at the top rater than the bottom.

Every Penjamin Pocket is made with 100% breathable and high quality cotton. Compared to others who may make their vape pen pockets with synthetic or acrylic yarns which are made of plastic microfibers. These microfibers can easily stick to the cartridge. Cotton yarn is more breathable than acrylic yarn and also handles heat more efficiently if your device tends to get hot. We use high quality cotton so you can keep your penjamin cozy without the potential of inhaling plastic microfibers.

Most pockets are designed to fit a standard 510-thread battery and may not fit a flat battery. Please check the individual listing to make sure the length and width will fit your battery before purchase.

There is a hole at the top of each cap to allow the tip of your pen to poke through for easy access. This cap can be adjusted on the lanyard to hide the top of your pen or keep it out of the sun. You can also pull it down further to expose the mouthpiece without having to take the cap off. The hole at the top of the cap also allows the use of pens that may be longer than 5 inches.

The tip of your pen will poke through the top of the pocket, reducing the amount of lint compared to keeping it in your pocket. Additionally, the pockets that come with caps, such as the mushrooms, allow for the tip of your pen to poke through the top unless you want to keep it covered for discretion.

Most pockets are designed to fit a standard 510-thread battery unless otherwise stated. Please check the size on each individual listing to make sure it will fit your battery BEFORE purchase.
