I'm selling these masks because my child has outgrown them, even though I bought them in bulk. They are made in Japan, so you can be assured of their quality (^^) They have two wires for structure, are breathable, and the thick elastic ear loops are designed to be gentle on the ears. The design makes it easy to breathe, so they are suitable for people who dislike masks and for children (•‿•) The ice blue color is suitable for both boys and girls. I have more in stock, so please comment if you would like to purchase multiple packs (^^) 【Product Description】 Ice blue, small-sized HYPER BLOCK MASK, 30 masks per pack. - Brand: elleair - Made in Japan These ice blue, small-sized masks, with 30 masks per pack, use a 99% cut filter to protect against viruses and pollen. - Brand: elleair - Product Name: HYPER BLOCK MASK - Size: Small (15.5cm x 9cm) - Quantity: 30 masks per pack - Color: Ice Blue - Filter Performance: 99% cut filter
