The 20mm square plain base is a compact infantry format for tightly arranged rank-and-file units, particularly in historical mass-battle systems and classic fantasy collections. "Plain" describes the flat base type: there is no slot or raised lip. Each base is injection-moulded from matte black ABS with sharp square corners and a fine, even texture across the top. This surface gives paint, adhesive, sand and other basing materials more grip without imposing a heavy scenic pattern. Compact footprint for dense infantry formations. Flat plain design with no slot or raised lip. Fine textured top supports paint, glue and basing materials. Sharp corners allow bases to rank up closely. Injection-moulded in matte black ABS. Compatible with popular tabletop miniatures; not affiliated with, endorsed by or produced by Games Workshop.
