We have the answers (we hope)

We have provided several small holes in each map to allow hanging of your map. Two or more finishing nails do a great job holding the map up and the heads of those nails are small enough to fit through the holes so you can take your map down to add more caps. Our custom hanger (sold separately) creates a shadow look and makes it easy to pop the map off to add more caps since the caps are added from the back. Screws are not included with the hanger.

Here's a video showing the hanger.

Each map is cut from 5mm thick plywood with a unique grain pattern that makes every map one of a kind.

Your map will have a single treatment for protection against absorbing water from the air. This does mean, however, the map may be at risk of warping over time and/or absorbing moisture. If you are planning on displaying this outdoors (or just want to ensure you indoor display is bullet proof) we encourage you to further seal and protect your Beer Cap Map to keep it looking great. This will not affect its ability to hold caps.

We have done our best to create a hole shape and size that will accommodate most bottle caps. This design is patent pending. There may be caps out there that will be too large or too small, and we apologize if that is the case. Caps that seem too large are often the result of bending during removal from the bottle and a little straightening out by hand will do the trick. Caps that are too small may require a little bending or even a small dab of super glue to ensure you can display them. To install into wooden maps, press the caps in from the back side to allow the caps to deform a bit and "stick" inside the holes.  This video demonstrates filling up a map.

The custom hanger is made exclusively for our wood maps. Since you put caps in from the front of the metal map, there is no need to take it off of the wall to load it up. Also, the corrugation naturally holds the map away from the wall, creating that cool shadow effect. So you can use the large holes provided in a few locations to screw the map to the wall or hang from picture hooks. The holes are hidden behind caps so you won't see the hardware. The metal Groove map weighs about 5 lbs without caps.
