The Crystal Collagen Eye Mask is a skincare product designed to provide nourishment and hydration to the delicate skin around the eyes. While I don't have access to specific product information, here are some common specifications you may find for crystal collagen eye masks:

1. Material: The eye masks are typically made of crystal collagen or hydrogel, which is a gel-like material that adheres well to the skin.
2. Ingredients: The eye masks often contain a combination of collagen, hyaluronic acid, vitamins, and other skin-nourishing ingredients to provide hydration and improve the appearance of the under-eye area.
3. Shape and Size: The eye masks are specifically shaped to fit the contour of the under-eye area and may come in a standard size or be adjustable to fit different face shapes.
