From the update:
The sheet will have a square format 30 x 30 cm. thickness of about 1.5 millimeters, flexible and workable with a cutter or scissors to adapt it to all surfaces.
The design as you can see from the image will be a paving stone.
Ideal as a base to lean above the buildings of the village.
But the most important thing is that these sheets will be a bonus reward for all the perks of the campaign, of course in addition to rewards acquired for funding.
Stay tuned for details. Lorenzo
