Timer padlock that can be locked for 1 to 99 hours. USB charging compatible, perfect for protecting smartphones and snacks. - Type: Timer padlock - Lock time: 1 to 99 hours - Color: Black - USB charging: Supported - Size: 46mm x 40mm x 20mm I bought this thinking of using it for a pet cage, but it didn't fit, so I'm selling it. I only attached it once as a test, but as you can see in the fifth picture, there are scratches on the dial. The dial has scratches because it is designed to be reset by removing the sheet on the dial. Thank you for your understanding. Thank you for looking.
