Thank you for viewing! This is a balance board recommended for toddlers to lower elementary school children. You can train your core balance just by riding and playing on it. (It might be too easy for children in middle school and older.) It's also recommended for physical training to prepare for entrance exams. As a precaution, it's a good idea to take measures to prevent scratches on the floor. It has been wiped down with disinfectant wipes. The item was used indoors by a child, so there are some minor scratches, but there are no noticeable scratches or stains. Please understand that this is a used item before considering a purchase. Size: Approximately W58 x D13 x H9 cm. Please note that the item may be shipped in simple packaging or in recycled cardboard. ※For reference: There are no smokers in the household. ※Instant purchase is welcome. #balance board #kids balance board #children's balance board #balance board kids #balance board children #entrance exam preparation #children's training #kids training #toddler training #educational toy
