GRAV Labs 16mm Taster w/ Silicone Skin What's better than a GRAV� Taster? A GRAV� Taster you can throw across the room without breaking it.The silicone skin on the new 16mm GRAV� Octo-tasters is as bouncy and shock-absorbent as any rubber. The pinched mouthpiece acts as an ash catcher, and the cap at the end of the taster keeps your bud in place, making the new assembly truly pocketable and portable. The entire silicone skin comes off for easy cleaning, and you can just peel back the end cap during use. And instead of a normal restriction, the taster has a glass screen for an extra layer of filtration.
