Japanese-made mesh swim caps, a set of two in blue and light blue. Colors: Blue, Light Blue Size: M Opening Diameter: Approximately 21.5-22 cm Used approximately 2-3 months, 3 times a month. Washed on the same day each time, so there are no stains. The inside tags had names written on them, so they have been blacked out. The color in the 6th photo is the closest to the actual color. Thank you.
