Made-in-Japan Cardboard Boxes - Size 60 for Delivery - 25 Sheets Perfect size for sending via anonymous Mercari delivery service, with a nationwide shipping fee of 750 yen. I have excess stock because I bought too many, so I'm selling them in smaller quantities. The unit price per box decreases if you buy a large quantity, but it's difficult for me to store a large amount, so I think this is a reasonable price, including shipping, even for a small lot. The company name and PR of the cardboard box manufacturer are printed on the blacked-out area in the photos, but please refrain from purchasing if you are particularly concerned about this. (It's commonly used in many online shops as well) Internal dimensions: 264 x 194 x 114 (depth) mm External dimensions: 270 x 200 x 126 (depth) mm Total external dimensions (3 sides): 60cm Box type: A-style Flute: B/F (3mm) C5 (160g/㎡) ★ Please be sure to read the notes in my profile before purchasing. ★ Instant purchase OK Anonymous Mercari delivery with free shipping ★ Please refrain from purchasing if you are nervous about the item, as it is stored at home. ★ Please understand that this is a layman's inspection before purchasing.
