This is a holder I bought at a vocational school. I haven't used it much. I'll include a calculator test form as a bonus. Feel free to comment if you have any questions. Q&A 1. When will you ship after purchase? A: Basically, small items will be shipped on the same day if purchased in the morning, or the next day if purchased in the afternoon. Large items will be shipped the next day. 2. Can you ship anonymously? A: Yes, I can ship anonymously. 3. Can I negotiate a discount? A: It depends on the item. Some items are negotiable, and some are not. ※Notes You cannot change the shipping address after purchasing the item (because it's anonymous shipping). When purchasing an item, please make sure to double-check your receiving address to avoid any mistakes.
