Hi Mary, Thank you for your feedback on our Chewable Helix Pendants. We're sorry to hear that it didn't meet your expectations and wore out quickly. You might want to consider a different shape chew, or perhaps a firmer one, as these factors, combined with the way in which your child chews, will impact on the langevity of the chew. We hope you are able to find one that suits. Please reach out if you require further assistance.
