This is an eyelash curler product.

This is the OA Petit Curling Eyelash Iron. It features three heat settings and a silicone tip, so wiping it with a wet tissue after use effectively removes mascara and allows for hygienic use. It is rechargeable via a C-pin, so it is convenient as it does not require batteries. It is also reversible, making it easy to use the top side for upper lashes and the bottom side for lower lashes. The heat is quite high, so the highest setting gets pretty hot. I definitely noticed a difference in how long the curl lasts with and without the iron, so I highly recommend it.
