Approximately 3 meters of white, soft elastic for hats, adjustable fit. - Type: Hat elastic - Color: White - Length: Approximately 3 meters - Material: Soft type - Application: Adjusting hat fit You might need to replace this a few times during the six years of elementary school. What do you think? The one on the left has been opened but is unused. I think I used the one on the right once, so there's still quite a bit left, and I'm selling them together. The one on the left is soft, and the one on the right is a little firmer. Thank you for looking.
