Battery Replacement Functionality Confirmed Colors: Gold, Red Please note that the color may appear slightly different depending on the viewing device. Regarding the waterproof function, it is unconfirmed due to its specialized nature. Please check it yourself. Tough Solar and rechargeable products are listed after being charged for 1-2 days, but they are used items, so the operating time may be shorter. Please rest assured that the items have been purchased and authenticated by qualified appraisers in the used brand auction market. Please understand that these are used items and may have scratches, rust, stains, or odors. Please purchase after viewing the photos. Please refrain from purchasing if you are sensitive to these issues, as the items are inspected and stored by amateurs. The items in the photos are all that are included. Items that can be disassembled will be shipped disassembled. We will pack the items carefully, but because we are offering them at a lower price than the market value, we may use simple packaging such as paper bags, cardboard boxes, and bubble wrap, and the items may be shipped folded. Thank you for your understanding. If you have any questions or concerns, please leave a comment. Returns are not accepted.
