They fit my henry schenier lancet pen perfectly. These lancets are good quality, work very well.

These fit both my cvs and keto-mojo lancing devices. Much sharper than the less expensive ones. Cost is affordable use for diabetics.

I have two different keto mojo lancet devices, and the needle is too short for both of them. It's possible i could shave them down with a craft knife, and might do so if i ever run out of the correct lancets, but that's unlikely.
