Blank hex and square grids are the perfect tool to help you set up your wargaming table or draw your wargame maps. A few marker pens are all you need to get started. In a pinch, you can use these A4-sized paper grids as wargaming mats, as well.
Available in 20mm square and hex grids.
20mm in hex refers to the inner diameter (length between opposing end points), not the hex sides.
