This is an ABUS COMBIFLEX TRAVEL GUARD. I am selling it because I will be using a different lock and no longer need this one. To check the functionality, I changed the key number once and then reset it. (It has been reset to 000.) ・Weight: 80g ・Size: 45cm (diameter 13cm) ・Lock type: 3-digit dial (number can be set) Please note that this is a used item, so please be aware of this if you are sensitive to such things. I have been informed that there are cases of product substitution, so I am sorry, but returns are not accepted. The following is an excerpt from the product description: Don't just hang your helmet on the handlebars, or leave your backpack unattended. Basic protection is very easy. The Combiflex TravelGuard can quickly and reliably lock bicycle helmets, bags, skis, strollers, etc. It's perfect for breaks on the go and can be stored in your pants or jersey pocket. Whether at the bakery or the ski lodge, this is an easy way to protect your belongings from theft. The very sturdy steel core and 3-digit code provide secure protection. The numerical code can be set and changed individually. The 45 cm long cable forms a lashing loop, and the length can be freely adjusted. This flexible construction allows the cable lock to secure things in various ways in everyday life, and to easily secure your property. There is nothing to disturb a quiet coffee break.
