This is a clever design for a serving tray. When you carry it by the handles, the 2" high rigid walls help keep everything contained, but as soon as you set it down, the walls flatten, conveniently converting it to a placemat.
Easily stored flat or upright, each reversible tray (gray on one side, black on the other) has a durable imitation-leather surface that’s heat resistant to 194°F (90°C) and easy to clean with a damp cloth. It can also serve as a base for anything from a table centerpiece to a craft project you need to move out of the way without a fuss.
The small tray measures 14" x 10" x 2" (17 1/2" x 13 1/2" when flat); the medium tray is 18" x 12" x 2" (21 1/2" x 16" when flat).
