I am selling the Shakti Pillow as I don't use it. The following is from the official website: The Shakti Pillow is designed to target the neck and shoulders. It fits comfortably under the neck like a sleeping pillow, providing gentle and effective pressure. Each pillow uses the original strength spikes and can be used alone or in combination with the Shakti Mat. The Shakti Pillow can also be used under the hamstrings, calves, and thighs to aid in muscle recovery after training. 42cm x 16.3cm x 11cm, 440g It comes with the box as shown in the photos. I have opened it to check the contents, but it is unused. Please understand that this item has been stored at home, and those who are concerned about minor details should refrain from purchasing.
