【Cultural and Creative Product】 Have the Best of Both Worlds – Double Shackle Lock(105年)
The barbed springs lock is most popular and wildly used in ancient China. It uses the key head to squeeze the barbed springs to open. Double shackle lock is very delicately designed. There are two keys to insert two keyholes to slide out two lock shackles in order. In such a design, even if a stranger has the right keys, it is difficult for him to open the lock.
