Clip on hooks for canes (at 22mm  7/8 inch diameter) to hang from a chair back, edge of a table, etc.   Small one for chairs w/o back padding, larger one for chairs with back padding.  My niece has both on her cane and uses the small one when she plays cards and the larger one at church to hang from the pew in front of her.  She just turns the hooks to use and back to switch to the other one.
