Due to the handmade nature of Shakti products, this can happen on occasion. Luckily it’s an easy fix! If you still have both the spike and back disc, you can reattach them by simply pushing the smaller disc up through the fabric, and then clamping down the spike on top so both parts connect (something heavy like a book will work well). You should hear a “click” when the spike is attached to the disc.If the spike/clip has been lost, let us know and we will get replacements in the mail for you as soon as possible. Please contact us with your order number and we can arrange this.
