This is a compact electric foot bath. It has a bubble function. Functionality was confirmed in December 2025. How about using it while reading? I've uploaded photos of the enclosed instruction manual. Please refer to it for usage, maintenance, and product specifications. Please note that there is damage to the side. While the appearance is affected, there are no issues with the functionality. By the way, I have kept the broken pieces from that area, so if you wish, I can repair it with super glue, or I can include them with the product.
