First Aid Microwaveable Flax Seed Pillow for Knees, Arms, or Low Back with Adjustable Closure from

I have owned this product for years and I still think it is the best one out there. The main reason is that it is segmented in three compartments filled with flax seeds, instead of one long one like most other long flax seed bags. The distribution of the seeds is much easier to achieve which facilitate the use of the wrap in all positions. Enjoy!
