This is an eye mask (eye sheet) to be applied under the eyes. It's a jelly-like texture, so it's best to avoid using it while your face is still wet from your final skincare step. I sleep with it on, and it lasts until the next morning. There are 20 applications per box. The box is slightly crushed, sorry about that. The retail price was a little over 2,000 yen per box. Available for immediate purchase.
