The tips of these tweezers are made out of ceramic. Ceramic will withstand high temperatures which is a necessity for the builder.

Warning: Do not use excess force on the tip when in contact with heat as ceramic might crack and/or shatter.

Rebuildables are for experts, not average or beginner vapers with no experience. These materials cannot safely be used by the inexperienced or those without basic knowledge of electronics.
