Shipping via Takkyubin (size 80). All items are A4-S size. Thickness: • 3 ring binders: 3 cm • 3 binders (punchless files): 1.5-2 cm These are items stored at home. I believe the condition is not bad, so please consider them for reuse and understand that they are pre-owned. For packaging, I will use used paper bags and other materials I have at home.
