Cute but defective
This was a nice tray but unfortunately one of the corner snaps was defective. I wanted to exchange it but that option wasn't available so my Valentine decided that he would keep the defective version. The tray has a nice message on it and holds quite a bit. Solid material. Poor quality snaps .
