Thank you for viewing! This is a brand new BTR15 purchased in May 2025! After purchasing this, I ended up buying the BTR17 without opening this one, so I'm putting it up for sale. Although some time has passed since the purchase, it has been carefully stored in a cardboard box in a place away from direct sunlight! You can purchase it for 3000 yen off the current Amazon price + free shipping, so please consider it! *Please note that I am not considering any further price reductions for this product.
