Pleasure + strength

I'd avoid glass balls and use metal. Although we have a ton of glass dildos and love them - having pieces of glass clanging together frequently seems like a recipe for micro-cracks eventually resulting in failure (breakage).

yeah there are a huge selection of vibratings ben wa balls in here ,, these are glass and yes go to the page were all the selection is see the reviews and the functions ,, to see which one you like more i cannot say which one is the best ,, because everyone it´s different ,, i hope there´s one right for you ,, good luck
