New revolutionary concept! Oli&Carol's Artichoke Rattle Toy is the GREENEST RATTLE IN THE MARKET! Its exterior is made of 100% natural rubber, and inside are upcycled cherry seeds that turn this teether into a rattle. 2 in 1. This rattle toy has been designed hand-to-hand with certified otorhinolaryngologists, to create the perfect sound pitch that will help babies calm down, rather than overstimulate. Filled with incredible textures & details that will help stimulate baby little one's senses while teething on them. Great stocking stuffers during the holidays!
