These are GREAT. The art is awesome and puzzle locking seems like it should have been the frist thing anyone thought of for Dungeon tiles. I do like magnet tiles but honestly these are just as fast and don't move around from each other. Also, the maker is smart enough to allow limited license ' meaning you CAN SELL your prints (but not the files or mass mold them). I print and paint and add LED lighting to my dungeons and if I want sell completed models these are great. I like these very much and am looking forward to addition set coming out!
