There are 40 Clothespins of 4 colors for 40 pairs of socks. YOU SAVE: TO STRETCH the socks one by one using both hands, now you can use one pair in each hand; - ASSEMBLE the socks take time and there is the possibility of losing one; - FOLD SOCKS because it is better to keep them with the clip and KNOW WHO OWNS IT, because each person has a color and can also USE IT TO HANG AND SEPARATE THE LINGERIE FROM OTHER ITEMS. It takes up less space in the clothesline, does not rust, does not damage or make noise in the washing machine. THIS PRODUCT IS NOT A TOY. LIKE ALL SMALL PARTS, THEY POSES A CHOKING HAZARD IF ACCIDENTALLY SWALLOWED. Note: The data are all measured manually, please allow 1-3cm error due to differences in light and display, there may be some color differences, please refer to the actual item received.
