Thank you for viewing. This is a set of a U-lock and cable, a standard for locks and cables, from Saikousha (SAIKO). Aluminum Shackle Lock WALX-8M P Color: Pink Weight: 280(g) Internal Height: 110(mm) Internal Width: 78(mm) Thickness: 14(mm) ￥1500 Crystal Prince 2000mm STN-1420 ￥2300 I used this for about 3 months when I lived in a place where I was worried about leaving my bicycle parked outside (it was in a place where it wouldn't get rained on). I haven't used it since I moved, and it has been stored away. Although it was used for a short period, there are some scratches on the U-lock, but it is a sturdy construction and there are no problems with its operation. Also, it is surprisingly light (280g), making it convenient to carry around. There are three double-wave keys. Also, as shown in the last photo, there is a spare key system. You can notify the manufacturer of the serial number on the card to have a key made, so you can rest assured in case of an emergency. Please check the condition and size in the photos (the faint black smudges in many of the photos are dirt on the lens, so please ignore them). Thank you for viewing, and please purchase if you understand. Thank you for your consideration.
