Query: Buttons gone

Bought four of these for our new tandem. One was delivered without buttons. One had a broken (split in two) button. The other two cages were ok but I don't have a matched set. After several rides the two cages seem to work ok but some bending was necessary for a good bottle fit. Black glossy finish was acceptable on all four cages.
