The colors are clear and vibrant, without being see-through, making them look like real fish (*´╰╯`)♬ Pin badges can be used in various places, and unlike magnets, they won't fall off and get lost, so you can use them for a long time ( ¨̮ ) When I attached them to a cap or bag and took them off, there was a small hole. The hole disappeared when I smoothed it out with my hand, but it might depend on the material. Please be careful with expensive or important items. You can attach them to disposable masks without worry!! I thought the clasp on the back would bother me, but it wasn't that noticeable! Since the size of masks varies from person to person, please use this as a reference... Shipping will be via regular mail. It takes 2-4 days depending on the location.
