The Ooze Shatter-Resistant Rolling Tray is the perfect piece for those who love the sophistication and class of a glass tray, but are prone to accidents and breaking things. We use a super strong glass that is legitimately shatter-resistant. We've thrown them around our warehouse, dropped them outside on the cement, and slammed them down on tables without leaving a single chip or crack! While these trays are incredibly durable, they are shatter RESISTANT and not shatter PROOF. We do not cover glass of any kind under the Ooze Warranty Program, so still take care when using your glass rolling tray! These rectangular trays are thick with edges that curve up to keep the ground bud collected in the center of the tray.
