If you purchase multiple items, please comment before purchasing, and I will combine them. In that case, for each additional purchase, I will deduct 150 yen as a shipping discount. If you purchase separately, no shipping discount will be applied, and items will be shipped separately. ~About Shipping~ Basically, items with a small number of parts will be shipped via Post Mini, and items with a large number of parts, such as bundled items, will be shipped via Rakuraku Mercari. However, depending on the product, I may change from Rakuraku to Yuyu after purchase.
