The 40mm square plain base is a larger ranked-model format for heavily equipped infantry, monstrous infantry, cavalry and smaller creatures. It provides a broader footprint than the 30mm square while remaining suitable for organised formations in mass-battle and historical systems. "Plain" identifies the flat, unslotted design with no raised lip. Each base is injection-moulded from matte black ABS with sharp square corners and a fine, even top texture that helps paint, adhesive, sand and scenic basing materials grip.

Suitable for smaller monsters and heavily equipped models.
Flat plain design with no slot or raised lip.

Injection-moulded in matte black ABS with sharp corners.

Notes · Q & A
Can I add magnets underneath OBS bases?+
Check the selected option's underside opening and available underside depth in Technical Specifications before choosing magnets. Magnet fit depends on the actual cavity dimensions and the magnet you plan to use, so it should not be assumed to be the same across every base.
How do I choose the right base size?+
Start with the base footprint required for your model or game, then confirm the selected option against the Technical Specifications. If you are replacing an existing base, measure it carefully and compare its physical footprint before ordering.
How should I use the technical drawing?+
Choose your option first, then use the technical drawing and Technical Specifications to check the physical dimensions of the product. When matching an existing part or accessory, use the drawing rather than relying on the product name alone.
Can I rely on the nominal size alone?+
No. Products with similar nominal sizes can have different physical dimensions or fit differently across brands and systems. Check the technical drawing, specifications and any product-specific compatibility note before ordering.
