I mean the options of the three attachments is great however the cup that fits over the head of the wand is very thinly made and when you turn on the vibrations it tends to slip off and does not provide much stability at all for the rabbitshaft part of the pal

The other two are three and a half inches

Theyre made of silicone and are designed to attach to the head of the hitachi magic wand and the magic wand rechargeable

The attachment cups are soft flexible and sturdy
