These are absolutely the best duo balls available worldwide.  The others are simply no match.  They are made of silicone and won't absorb odours, bacteria or dust.  Making them much more hygenic than standard duo balls. (Which normally has cotton strings attaching them, making them more absorbent of bacterias.)

The movement within them is also considerably smoother and will produce a much nicer sensation.  As far as duo balls go, we couldn't recommend anything more highly.

Why we loved it:

• Silicone material is extremely comfortable and hygienic.
• Smoother movements.
• Silicone cord, unlike other duo balls which normally use a cotton cord - making it a much safer toy.
• Will last you a lifetime.
