Released in 2017. I bought this for overseas travel, but I rarely used it because I used the hotel safe and carried valuables with me, so I'm selling it. I think it would be useful in hotels without a safe or for outdoor activities. It's unused, but please understand that it has been stored at home. There are no instructions. * As shown in the 8th photo: ① Press the release button on the left side while selecting the numbers for the dial lock. ② Release the release button. ③ You can change it to the number you decided on. * It is set to "000" when shipped, so please change it to your preferred number when you receive it.
