The red Lavender Eye Pillow is made from the scraps of our 92% organic cotton, 8% lycra fabric. We fill these with organic lavender and flaxseed. This is a wonderful tool for relaxation or gift to a loved one. The organic eye pillows can be heated in the microwave for additional comfort. To use your pillow, warm it in the microwave for about 30 seconds. Shake and warm for another 30 to 60 seconds, until the desired warmth. To warm it in the oven, place in cold oven and turn heat to 200 degrees. Shake pillow after five minutes, then replace for another two to five minutes, testing often.
