Review on 🍽️ HQRP 11.25-inch Glass Turntable Tray Inclusive of Sharp 9KC3517203500 R309YK R309YV R309YW R318AV R331ZS Microwave Oven Cooking Plate by Dave White

It was exactly what I was looking for and they did a great job. They are very thin so you need to look carefully to make sure you separate them all. I received the exact number that is stated on the package. You also need to work slowly so the panes don't slip when you place the glass top on the furniture. The disks appear to "magnetize" (like static electricity) and shift. Someone wrote that they are very thin and don't protect like other furniture "cushions". But that is not the purpose of this type of surface protection. According to my furniture varnisher they are used to separate a sheet of glass or other piece/object from the top of your furniture and you want them to be thin and you don't need thicker bumpers or glue to do that. You need "delimiter". That's it. They "separate" the glass from the countertop. Ideal.
