I love these, this is the 2nd lot I've bought. The little yellow dots you see are made from silicone and really grip plates well. I've had my first lot for 6 months now. Very easy care. OK to put in the dishwasher too. They hold a GENEROUS serve of sauce or dip. Easy to clip onto your own plate or you can clip a couple on a serving dish at a party as well. I've never had an issue with them staying on. Totally recommend these :) Also great for finger paints for the kids or holding beads etc for craft work ♡♡♡ Arrived in a month, way ahead of the predicted time.
