Thank you for viewing. This is a Mizuno vinyl knapsack. This is a set of 5. Since it's vinyl, it's basically disposable. However, it's not thin vinyl like a plastic shopping bag, so I think it will last a decent amount of time. Height: 47.5cm Width: 38cm Depth: 10cm The price includes nationwide shipping. I am very sorry, but please understand that the price of this item cannot be reduced.
