These are a support that follows the contour of most standard size disc golf discs that allows the use of small command strip stickers to adhere them to the wall. I have noticed that occasionally they do not stay adhered to the command strip so I use some CA glue to ensure they stick to the strip before mounting them the wall. This is issues was just observed with PLA plastics I'm not sure if other plastic types would fare better with the command strips without the extra glue.
