Thank you for viewing. This is a U-lock purchased on Amazon. *Please read the description to the end... and then comment before purchasing. ◯ Reason for listing I used this on my motorcycle a few times, but I haven't used it at all since I switched to a high-performance lock key. There is one key. ◯ Size If you wish, I will measure it, so please comment. ◯ Shipping method We also support Yu-Yu Mercari delivery! Shipping is included, so it's a great deal! If you have any questions, please feel free to comment. I hope someone who can use it in their daily life will purchase it! If you purchase other items together, I will offer a discount. The following are important notes. *Please comment before purchasing. Please see the photos for scratches and dirt. Please refrain from purchasing if you are looking for the same quality as new. I would like to sell it to someone who can use it on a regular basis. We may refuse to sell if we determine that the buyer is a business (e.g., an unusually large number of new listings, excessive use of emojis).
