Thank you for viewing. This is a backpack from the popular sports brand Adidas. The product number is ABM001 024390. The size is 45cm in length and 28cm in width on the back, and 17cm in width at the bottom. Please allow for some error as this is amateur measurement. It is used, so there is a feeling of use (damage to the bottom corners, fabric wear and color fading due to use - please check the images), but if you don't mind the details, it is still in a condition where it can be used a lot. Would someone like to use it for themselves or as a spare for their child? We are looking forward to your purchase if you understand that it is used and agree with the condition of the product as described. Thank you.
