These are the neatest thing you will ever use or see! I absolutely love using them and I myself use them ALOT! The do not tip over and they take up the smallest amount of room! I’m a messy crafter so I always have a ton of stuff on my desk and when I need to sit my wet cup down or take it off the turner and let it finish curing I stink the cup on these! Keep the cup on your PVC and just slide the PVC right over the stand! This fits ALL size cups and ALL size PVC...Also these come in 2 pieces the cross section and the stick. The long part will fit inside the cross section securely. It’s a very snug tight fit so no need to glue unless you just want to. The have nonslip stoppers on the bottom that keep the stand from sliding and scratching any survive areas.
