Made of grade 2 titanium these 14 mm nails are considered the basic grade for heating any herbal extract or bong for vaporization purposes. With a highly polished surface these 14 mm nails are very easy to carry and use in any type of vaporizer. In many metallic plates made of other metals a residue may be deposited on the metal surface due to regular use or intense heating which is practically negligible on a titanium nail. The ti nail concept comes new for vapor globes and also looks highly fancy on any glass dome vaporizer when using the vaporizer collectively for smoking purposes
