The Competition Mod Holder is made for those committed to vaping big clouds! It's the perfect Vapesox creation for your cloud competitions, e-juice flavor tasting competitions, and more. The two sleeves on the inside hold extra large sizes like the 26650. And they're tight enough to hold an 18650 mod. There are two elastic holders for your E-Juice and a small pouch for anything else you'd like to carry: Batteries, Vapor Rag, ID and Money, etc. Carry with the attached handle or use the belt clip to attach it to your belt!
