I purchased this three years ago and used it for about two years. I haven't had a chance to use it since moving, and it's been in storage for about a year. Currently, I don't have an environment to test its operation, so its functionality is unconfirmed. Please purchase only if you understand this. The double-sided tape on the back has been used, so please prepare new double-sided tape if needed. There is no box or instruction manual. *Please consider this item, understanding that it is a used item with unconfirmed functionality. Shipping will be via Rakuraku Mercari Bin or Yu-Yu Mercari Bin. Both offer anonymous shipping. Due to amateur storage, there may be overlooked minor scratches, etc. Please feel free to comment if you have any concerns. ✔ No smoking ✔ No pets ✔ I am committed to careful packaging and prompt shipping. Thank you very much.
