Review on Enhance Your Culinary Experience with Certified International Talavera Multicolor Food Service Equipment & Supplies by Roberto Evans

I bought this tray primarily to bring drinks and food out onto the patio. Unfortunately, the tray is a bit convex and slippery, so the glasses slide on it and almost fall over. I don't understand why the tray can't be made completely flat. It's nice, but right now I'm mainly using it to save post, so the theme isn't visible anyway.
