This quartz banger is one of our highest quality products available from Quave Club Banger. The banger is equipped with a 25mm bucket that has a wall weight of 2.5mm and a healthy 4mm thick flat bottom that is 100% flat for ultimate terp pearl spinning assurance. This is the perfect model for retaining the most heat in the banger and providing the highest quality of flavor for your dab. Cool down times range from 70-80 seconds depending on how hot you get your nail. On the top rims of the bangers, we have the option of having a regular flat top or a beveled rim. The beveled rims help create an optimal lock for the bubble caps, allowing them to work exceptionally well with low temp dabs with maximum heat retention. The regular flat top rims are most commonly found while using maria caps, (caps that rest horizontally), and are secure to the core. To each his/her own, whatever floats your boat. We are a workforce united to bring forth the highest quality of aesthetics to the banger.
