Prevents your toddler from ingesting harmful varnish. The Prince Lionheart Crib Rail Teether is made of Phthalate free, non-toxic soft plastic that easily slips over your crib rail to protect Baby's new teeth and tender gums from nasty bumps and falls on hard rail edges. No adhesives are needed, so when the Crib Rail Teether needs cleaned, just remove each section and place in the dishwasher on the top rack. Four 12 inch lengths are included to cover a standard crib rail. High friction, FDA approved plastic will not slide or pinch little fingers. Made in the USA.
