The Unique design of this cap allows for air to spin fully throughout the banger, and are most effective when paired with Terp pearl's, which can be found. Combine a spinner cap and terp pearls with a flat bottomed banger to allow your pearls to spin up to ludicrous speed. Warning: not many have achieved ludicrous speed during a hit and resisted a cough.

Color is assorted based on availability, but ranges between Purple, Pink, Amber and Clear

They pair up perfectly with 20mm bangers
