Can 2 pens of the same size be joined together? A. These pens are not designed to be attached together, however with a bit of tinkering and a pair of pliers someone who is a bit handy should be able to join two pens together without too much trouble. The pen's panels are connected with metal spirals, but the tips of the spirals have been purposely bent so that they don't move or come off. However, with pliers, you should be able to unbend the spiral tips so that the spirals can be spun and removed. Then once you have removed one of the panels and connected the 2 pens you can then re-secure the panels with the removed spirals. You can then re-bend the tips of the spirals so they will stay in place. Q. Is the medium size is available? A. This size was discontinued by Bono Fido and is no longer available. It went by the product code 40405.
