Arm Sling (Yume Fuwa Unicorn - Aqua Green) I purchased this new on Mercari. I used it two or three times, but it kept slipping, so I didn't use it much. This is a cute arm sling, recommended for those who want to cheer up their child. Please understand that this is a used item before purchasing. [Quoted from the HP: Size Notes] For children / up to 20cm forearm * For children up to approximately 125cm tall ・Children up to 125cm tall and weighing up to 21kg can use the "child size". ・Even if a child is 125cm tall, if their weight is over 21kg (like the model girl), the strap may not be long enough. The pattern is Yume Fuwa Unicorn - Aqua Green.
