Authentic Sigelei Silicone Cases for 100W or 100W Plus Box Mods, direct from Sigelei themselves! I personally have these devices (Box Mod and Attys not included) and I want to keep them safe and have them stand out from other box mods, and these precision cut silicone gel covers fit my 100 Watt Sigelei perfectly. All buttons and vent holes are kept open and cut to exact fit. Not to mention, the non-slip material keeps it comfortably in your hand or on whatever surface you want to set it on. I ship from Los Angeles, California!
