This is a foldable beer / soda can holder, for your needs. You can Hang in on your wall, in your boat och where ever you want. When you don't use it, just fold it together and it won't take up any unnecessary space. I use it for my belly boat when i fish so my name for it is: Baitbox belly boat beer buddy . There are two types of top rings. I added a tighter top ring with a small "stop". So that the ring i upfolded to the right position and stays there. Dimensions: length:11.5 cm width: 5,6 cm (7,6 cm for the top-ring) height: 1,95 cm (folded)
