These really help in deciding what size you should get, especially if you're between sizes.
These are definitely worth purchasing before ordering a full device! Same yourself having to spend even more in the long run and just get a couple to make sure.
These sample rings are very helpful in figuring out sizing
It's great that the base rings are available in loads of sizes in both round and anatomic shapes. Definitely recommended before ordering a device.
Definitely get this ring set. I messed up on my initial measurement which is my own fault and now I was in search for a new ring size and realize I had a big size difference. I wish Ibought the ring sizing kit before hand it would of saved me a lot of money!
