We've got a wand here (not bought from this site) and was wondering if all wands are the same size?
Reason is that the wife and I are going away for the night this weekend for our birthdays and so was wondering if the attachments would fit our wand, or whether a new purchase is in order
Short answer is, No - not all wands are the same size.
Most of the attachments on here need a magic wand that has a circumference round the head of 7.5 inches - So the Lovehoney Deluxe Magic Wand, The Doxy Extra Powerful, BodyWand Mains Powered or Lelo Smart Wand (Large) will all be suitable.
