These Twist Locks are BEAUTIFUL!!! They are sold as a set of 4 of the same finish. They are a very nice weight and proportioned just right to be stable on your bag or wallet. They are available in 4 finishes..Nickel, Antigue Brass, Gunmetal and Rose Gold. The actual twist part of the lock inserts into a slotted back plate, which will not be seen because it will be on the inside of your linings, between the interior and exterior. The part that your twist lock will go into has a solid front and back plate that attach together with 2 screws. The back plate does not attach with the wings that fold into the backside of the plate.
