I am taking one more shot at this thread and moving back to the top.... I can't believe no one sells these. My dd grip holes are too large and these look perfect. I would love the find a source for them. Anyone with some info,,,, please post!
These are available in the UK from a website called Gymnastic Express. They cost Â£2.55 and are called finger wedgies. I dont know if they send to the USA as it is not an option available when setting up a user account. I would be happy to order eg 10 sets and send on to somebody in the USA for reselling if anybody is interested. There is a Â£2.95 postage charge to the UK which covers orders up to Â£100. I would have to find out what the postage to the USA would be.
Anyway, let me know and we could organize something if they are not available to America.
I'm not trying to butt-in...and every gym owner in the world is going to want to kill me for this...but our kids just tear foam off a foam block which is already partly shreaded and stuff it in the hole. This way the foam can be custom sized depending on how big the hole is.
