Around a decade ago, RAW reinvented the rolling tray with the RAW Classic Rolling Tray. The rolling trays of the 1960s and 70s were thick metal with a smooth coating on top. They were created by old brands like the Italian CLUB rolling tray (which was the most famous one of its time).

RAW Classic Rolling Tray is available in Large, Small & Mini.
Large: 14 x 11 x 1.25
Small: 11 x 7 x 1
Mini: 7.25 x 5 x 0.6
