All natural hardwood teethers are one of the best toys you can give your child when they are starting to teethe. When your child develops the object to mouth relationship, you'll want to be sure that the objects they're putting in their mouths are either food or non toxic. These teethers are made from sustainably sourced North American maple and sanded smoothly so they are safe for baby. The wood is unfinished so there are no toxic chemicals anywhere on this teether. Made in the USA.
