I cherished these items so much that I kept them in a box for a long time. There is no discoloration. Thinking of the approaching cherry blossom season reminds me of Charmy ♡. I didn't get a chance to use them this year either, so I'd like to pass them on to someone who will! These are Japan-limited edition items, all four are new and unopened. ① Foldable Sandwich Case. A retro and cute sandwich case for cherry blossom viewing and picnics♪ Perfect for everyday lunches! Not just for sandwiches, but also for onigiri (wrapped in plastic wrap) as a case ◎ ② Double-walled insulated cup ③ Soft leisure sheet ④ Leisure bag Made of leisure sheet material, so it's very durable and easy to wipe clean. Easy to use with long handles that can be slung over the shoulder! ★ Individual sales are also possible, but I'd love for you to use them as a set & it's a better deal on shipping. Please consider the 4-piece set!! ■ I have multiple insulated cups and sandwich cases, so additional items are available. Please let me know before purchasing if you'd like more. ● I've set a long shipping time, but I can accommodate those in a hurry. ※ May be removed without notice.
