ABUS 4-digit combination chain lock model. Security level 7, with a long chain for easy looping and ground locking. These sell for around 10,000 yen when new. The 4-digit combination can be set to any number by rotating the red part near the lock. It is set to open with four white circles upon shipment. The chain has some minor dirt, but the cover is not torn and is still in good condition. There is some paint chipping on the dial and the insertion bar. Feel free to ask any questions in the comments.
