Natural-dyed 100% cotton denim These pillows are lightweight and designed to alleviate neck muscle tension and promote relaxation while sitting up. They are sewn in three sections so all the pits don't collect at one end. The Hot Cherry® Neck Wrap in blue denim gets its rich blue color from the indigo plant. Same great pits, and like all Hot Cherry pillows, can be used hot or chilled! Minimally packaged in twine wrap. Each Neck Wrap measures 22” x 5” and holds approximately 2 lbs. of clean dried cherry pits. * All Hot Cherry® pillows are machine washable ––follow instructions carefully–– and they will last for years! * Every Hot Cherry® pillow is microwavable and freezable. They can be used hot, cold or room temperature. * Hot Cherry® pillows come in six different sizes and three fabrics to choose from. * Hot Cherry® pillows are made with love in the USA.
