cock cage recommendation

So I've been having a nightmare trying to get a cage for my partner. We've tried plastic, metal, silicone in all kind of sizes and shapes but nothing seems to fit properly! Basically, he has impressively large testicles and the U rings just don't seem to work for him. Has anyone else had this problem? Can you recommend a better material for larger balled men or certain details I should be looking for?

Any help is much appreciated. Apologies if this is repeated elsewhere but most of the chastity threads seemed to be quite old. x

We have this:

It's super stretchy, takes a bit of juggling to get it on over the testicles bit it's comfortable according to my husband who has quite a pair.

Hope this helps you on your quest.

The CB range has a bigger ring that you can buy separately https://www.lovehoney.co.uk/product.cfm?p=31762

Ah! Amazing! Thank you both!x
