White Howlite is a calming, soothing stone that dispels anxiety and stress, making it ideal for encouraging spirituality, patience, harmony, and meditation. Our kids bracelets are made with a durable long lasting wax cord and tightly fastened to prevent breakage. We recommend inspecting the product prior to use to ensure safety as materials in this product can be a choking hazard.
