Thank you very much for viewing! These are iron-on name labels for underwear and sock sizes (*^^*) They can be applied to materials that couldn't be ironed on before, such as synthetic fibers and stretchy materials. In addition to an iron, they can also be adhered with a low-temperature hair iron (110 degrees Celsius) for 1 second. You can apply them regardless of the color of the material: white, black, light colors, or dark colors. Besides underwear and socks, they can also be used on gym clothes, jerseys, sports uniforms, and more. The labels themselves stretch, so they can be applied to rubber parts. They adhere strongly and can withstand repeated washing. You can purchase without a comment. Please provide the name you would like to include after purchase. These are uncut. Cutting corner guidelines are included, so please cut them with scissors or a cutter. Due to being handmade, there may be slight ink smudges or cutting misalignments. ★Size 0.8 cm (height) x 2.8 cm (width) ★Number of sheets Set of 51 ★How to use These are labels that are adhered using an iron or hair iron.

An instruction manual and a finishing sheet (a sheet to prevent the label from sticking to the iron) are included. A must-see for busy moms!
