The Smoktech Telescope Mod Clip is made of stainless steel and is designed to carry Zmax, Vmax, Telescope, and Natural mods. With silica gel clip covers it can clip Zmax/Vmax/Natural/Telescope mods very well, making it easy to carry those big mods around, especially when you go outside. Easy to hang mods on bags, key chains etc. Really good choice for mod lovers.
