Thank you for viewing. This is business card printing paper made by PLUS. It can be printed using laser printers, copiers, and inkjet printers. It's a thick, double-sided printing type. The micro-perforations ensure clean, non-jagged edges. Images 1-3 are from the manufacturer and are a different model number; the actual product is shown in images 4 and later. 30 sheets + α (extra for protection, not counted in the total) will be sent in a double-layered envelope (Kakukei 2, A4 size). I bought a large box, but I don't think I'll use it all, so I'm selling it in smaller quantities. This product sells for over ¥500 (excluding tax) for 10 sheets (100 cards) in online shops, but how about 30 sheets + α for ¥1,000 (tax included), including shipping? The easiest way is to use free business card creation software available online, but you can also find instructions for printing business cards using Word or Excel if you search online. Feel free to choose the style that suits you. Making your own business cards is fun because you can customize them for different purposes. Shipping will be via Yu-packet. Price reductions are not possible, but please consult if you would like to increase the number of sheets (e.g., 40 sheets, 50 sheets). A receipt will be included for those who request one.
