I think this can be used until early elementary school. Please refrain from purchasing if you are overly concerned about details. I am open to price negotiations! Please be reasonable. I also have other children's items, twin clothes, etc. for sale! #kaketakeSHOP Please take a look if you'd like! I will offer a significant discount if you purchase multiple items! Please be sure to check my profile before purchasing, as it may be a hassle.
