There are 30 masks inside the box! It is quite heavy! When I open this mask, it come with a small tweezer, which is quite clean, so that when I take the mask out, It might not be afraid of contaminating other masks! I use that tweezers take out one piece of mask, smell like fresh tea tree scent! When I take it out I see there are a lot of essence and it dripping! After I put it on the face, it feel very comfortable and soothing! Very moisturizing and locks the essence! So hydrating, calming and smoothing! I put it in the refrigerator after open this mask box. I think this way can keep other mask fresh! Great for this hot summer season, it feels so cooling ! It is so comforting! So relaxing! I like it!
