Since these soft 4" plastic balls have a bumpy surface, babies as young as 6 months can more easily grip them. And older children enjoy squeezing, rolling, throwing, or kicking them. The balls come fully inflated and can be re-inflated via a built-in "basketball pin" receptacle.
Use a clean towel or rag to wipe instruments with a natural cleaning solution. Items are not watertight, so do not immerse in water or place in the dishwasher. Allow to air dry. To disinfect, spray surface with a solution containing ½ teaspoon household bleach to 1 quart water, then immediately wipe dry with a cloth or paper towel. The use of commercial cleaners, chemicals, and solvents should be avoided to prevent compromising the plastic components.
