The outside of the rattle is made entirely of natural rubber, and inside there are recycled cherry seeds that turn this 2in1 chew toy into a rattle. The toy was designed hand in hand with certified otorhinolaryngologists, with whom we have been able to create the perfect pitch to help babies calm down instead of overstimulating them.
The ring design makes it easy for babies to grab and hold the toy. The soft material is safe to chew while stimulating the baby's senses and soothing itchy gums. The rattle is hand-painted with safe, natural dyes and is completely non-toxic and safe for children. Certified by Bureau Veritas.
There are no holes in any Oli&Carol toy to prevent bacteria or mold from growing inside the toy.
