CLESDF 6 Pieces Anti-Slip Tools Sticky Mat for Diamond Painting, Non-Slip Universal Gel Pad Mount Holder Tools for Holding Tray 5D Diamond Embroidery Accessories (5.6 x 3.3 Inch)

I bought these to hold the trays for my diamond art on. They are what you expect cheap and cheerful. We already had these that are sold for holding mobile phones in cars. Although they do hold the trays I found that if I needed to lift the tray off to shake it to get the diamonds in the correct position or to place left over 'diamonds' back in the small plastic bags that come with them the 'diamonds' scatter everywhere so I don't use them anymore.

I find them too sticky so it is difficult to get the tray off without sending the diamonds flying everywhere

They increase the diamonds ability to hold on and needing wax to pick up the diamonds unless you prefer tweezers like some people find easier to hold

Good to keep my cup on the table so as I am disabled I often spill my drink, but these help me. Good stick.

I ordered these to hold my light pad easel. It doesn't move at all now
