Revolutionize your setup with these heady glass diamond top caps. We love these caps as the smooth tapered tip allows the diamond tops to seal bangers of all sizes with ease. Compatible with bangers with a top diameter between 16mm-30mm (Auto-Spinners, Terp Slurpers, Samurai Blenders, etc). Made out of solid glass, our diamond top caps are available in Clear, Blue, Yellow, Pink, and Green. The top of the diamond is 30mm wide.
