This Rolling Tray from Greengo is made from recycled plastic. The plastic comes from the plastic boxes in which cannabis was sold. These are returned to Greengo through a deposit system. The factory grinds this plastic and produces Greengo ECO Rolling Trays from it. The Rolling Tray is sealed by a DOME sticker with a Greengo logo. The Dome sticker is made with 2 components, mercury-free resin.
