Kings Universal Male Pump Sleeve Vacuum Pump Suction Seal (Multicolour) -2 Set

Diameter is small.

Perfect work

Don't buy it!! It's a poisonous garbage plastic rubber yellow color material. Bad and poisonous smell always came from it after washing too many times. Material is a yellow color and it can make you sick by smell !!! Threw it away.

This product is worst when I tried to return it had a no reatur policy . So i had to throw it as I dont find any use of it .
