Suction cups can be an easy way to hang a crystal or suncatcher, dreamcatcher etc onto a smooth surface, eg a mirror, tile or window etc. Hang lightweight toys in the car to entertain the little ones, hang an ornament on a glass sliding door to prevent people walking into it (because your windows of course are SO clean they look like they aren't there LOL), hold up signs in shops, on a fridge, inside aquariums, fish tanks and the like.
The hooks included in the package, thread through the hole (skinny end first) to give you the hanger. You can use them without the hanger also.
Quantity: 10 suction cups plus 10 hooks.
Measurements: Cup is 3cm across
