4 Pcs Handheld Back Mini Massage Gun Attachments Accessories Hitachi for Back Neck Leg Pain Massage Come with Storage Bag

I was a little skeptical of these would actually be fun/ Pleasurable. BUT they are both, very good buy. My husband had a lot of fun using them on me.

The media could not be loaded. These are definitely NOT 50mm internal diameter… more like 40mm, when I measured this set. They fit, but require some work to get them fully seated on a toy that is 48mm in diameter, as pictured. Even then, if you look, you can see where there is a gap at the top (video).

Worked fine

Fantastic
