12/36/72 PCS Lumbar Spine Patch Long-lasting Warm Waist Body Soothing Self-Heating Pads for Athletes Office Workers

Got fooled by the item's picture and didn't pay attention to the patches' actual shape. I wanted the larger rectangular patches but got the knee patches. My fault for not paying attention, but it's still a bait-and-switch on the seller's part.

Excellent patches for various ailments, I recommend them.
