I don't know of any sleeves that would work for the location mats. The sleeves mentioned by the other two users work great for your boss mats, and the rest of the big cards for Tiny Epic games, like TEG's galaxy mats, but those location mats aren't a typical size.
I haven't heard of anything unless you wanted to have them laminated and then trim the extra off. If you happen to find a custom solution that works, please let us know.
If you dont wany to laminate, get sleeves big enough to fit the mats in, use an impulse sealer on the edges, and trim the excess. All the benefits of a sleeve, without the potential damage of the laminator. Need to replace? Trim off an edge and slide the location mat out.
Thanks guys. Yeah I was looking into something like Michael said. I have some simple plastic bags that I bought on the supermarket and that where large enough to fit the mats. So I went online and ordered a mini heat sealer (their cheap) and Im gonna try to trim/seal them in the mats shape and then just trim any excess with an exacto. Im waiting on the sealer to arrive, so I´ll let you guys know how it went.
