H-Art FDA Certified Foot Pads, 2in1 (20pcs) - Pain Relief, Antistress, Body Cleansing and Sleep Better - 100% Organic Foot Patches - New 2019 Formula

Place a damp cloth on the pad and it will turn black just like it would on your foot over night! Doesn’t do anything.

Use of this product directly resulted in sores that necessitated amputation of both feet. I will not be purchasing again as I no longer have feet.
