Color of the photo. (Blue) Hinge and black plastic clasp. Bellows soft plastic with 6 slots. In the two central squares plastic cards can be inserted back to back. In the bonded squares in the bellows against the wheels, providing only one card will be more difficult to extract due to the curvature of the object and the clasp. Let thus 10 seats maximum usable without forcing and without the risk of damaging the bellows. Very convenient for me for my loyalty cards, but use with caution.
