I purchased this keyboard about three years ago and have used it a few times. I am selling it because I no longer have a computer. I threw away the instruction manual, so please search online for it. This is the ELRETRON PENNA, a Bluetooth wireless keyboard with a retro typewriter-style design. • Color: Olive Green • Bluetooth 4.2 compatible, multi-pairing for up to 5 devices • Compatible with Windows, iOS, and Android • Includes a stand for tablets and smartphones • Uses German Cherry mechanical switches (either blue, red, or brown) • Key layout is English (Japanese input is also possible) • Keyboard only (no accessories), in good condition Operation has been confirmed, and there are no noticeable scratches or stains. Since there is no instruction manual, you will need to search online for it. Please feel free to ask any questions you may have. 【Important Notes】 • Batteries are not included (requires 2 AA batteries). • The key layout is English. Japanese input is possible, but the key markings are in English. Thank you for your consideration.
