Thermochromic Bucket/Banger/Nail - By Puffing Bird™
This is one of the most well thought out nails on the market today. There are two layers of glass with colored fritted glass in between. The colored glass serves as a replacement for your dab timer no matter where you go. You no longer have to find your phone, unlock the screen and find the timer app every time you want to dab. This is one of the best quartz bangers when it comes to convenience.
Colored glass will turn bright red when heated to the right dabbing temperature.
