Slurper/ tower cap purple and white uv

This cap is made for towers and slurpers, no air flow. The white is white satin under a layer of clear which gives a very cool effect. The white also goes hot pink under uv light. 17.5mm diameter in the center of ball section. Made to sit in the bevel of larger slurpers and securely on the smaller towers as well. Seals great and stands nicely upside down on the table, also has a roll stop on the side.
