Standard MediBeads® 9" x 12"

When microwaved, MediBeads draw moisture from the air and release it as clean, deeply-penetrating moist heat - no need to add water. Washable, odor-free, dust free, and will not support bacteria or fungal growth. Needs no special cover, as they will not dry out, dissolve or disintegrate. 9" x 12" size.
