  1. Can you do these without the rounded tops that could be used to cut & paste onto other existing tiles (docks, caverns, old dungeons) as well as other brands of 50mm tiles?

    • These do have flat tops, it’s only the trial pack that has the rounded top

  2. Can be used on a comercial project? (I mean, a dungeon with this system on his tiles)

    • Yes the OpenLOCK system is Opensource. You can use these templates to create your own tiles. If you want a commercial licence then we can give you one. Please contact us via the contact page for a commercial OpenLOCK licence

    There is no clip in this download. Is there supposed to be? I’m easily confused by which clip I’m supposed to be using!
