I could be a foot model now!!!
Size: 1 pair black L
I wear work boots almost all of the time so I bought these to put on my feet with salycylic acid to moisturize and try to get rid of a stubborn corn on the ball of my foot. It helped drastically after a few nights of lounging in the house with them on.

Nail Must Have💅🏽
I didn’t know I needed a double-sided nail mat until I owned one—and now I’m emotionally attached. This thing has officially become my manicure bodyguard, standing between my nails and the chaos of real life. One side catches polish drips like a champ, the other side keeps my tools from sliding away like they’re trying to escape responsibility. No more nail polish on the table, the couch, or my soul. Clean-up is so easy it almost feels suspicious. It lays flat, stays put, and makes me feel like a professional nail tech even though I’m painting my nails while watching TV and questioning my life choices. Bonus points for being reusable, washable, and silently judging me for painting my nails “just one more coat.” Five stars for saving my furniture, my sanity, and my dignity. If you do your nails at home, this mat is the real MVP. 💅✨

As described
This was a gift for our niece. She loves to paint her nails, and we noticed similar mats at the nail salon we go to - so we got her an age appropriate nail "studio" to gift along with it. My friend thought it would be great for laying out when coloring and painting also, because its large.
