These dolphins swim around in water bottles, baby bottles, wine carafes, and vases keeping bacteria at bay!

Each dolphin has a silicone ball inside the sponge to help loosen residue on the sides and agitate the water to clean hard-to-reach areas. To use, simply place a dolphin inside your bottle and shake, stir or swirl it around making sure it touches all those impossible-to-reach places.

Features:

• Sponge is made from polyurethane, with two silicone balls inside
• Set of 3 to clean multiple bottles at once
• Measures 7 x4 x 2 cm each
