Injection-moulded from ABS plastic — the same family of materials used in LEGO bricks. ABS does not warp, holds its shape over time, and bonds reliably with superglue (cyanoacrylate) and two-part epoxy. The textured top surface grips PVA, texture paste, and basing sand without needing to score or rough up the surface first. Takes all spray and brush-on primers cleanly.

Every mould in the OBS range is designed in-house using industry-standard CAD — these are not generic imports. We control the full production chain from design through to quality control. Mould lines are clean and consistent.

At 120×92mm this is a substantial oval — the 5mm total height and 2.04mm floor keep it rigid and stable under heavy monster and vehicle kits. 3mm of underside clearance fits 5×2mm or 5×3mm disc magnets comfortably. Use three or more spread in a triangle pattern for a balanced, secure hold in transport.

120×92mm oval is a large monster and vehicle base specification found across modern skirmish wargaming systems. Used for greater beasts, flying monsters, large cavalry, and medium vehicles in games that use oval bases for directional facing.

The 119.3mm outer long axis sits fractionally under the 120mm nominal. Correct for organised and competitive play in systems that specify a 120×92mm oval footprint. The oval shape gives a clear front-facing orientation — useful for charge arcs, line of sight, and movement in skirmish games.

Part of the Open Basing System (OBS)

One Ecosystem · Every Size · Every Shape

OBS is a modular basing ecosystem designed as a whole — not a random collection of bestsellers. Every size, shape, converter, and tray is planned to work together. Independent and gamer-built.

New products added regularly — the OBS range is always growing.

Wash before priming — a quick rinse in warm soapy water removes mould release residue. Let it dry completely flat before spraying.

Large monsters and vehicles often have small contact points for their weight. Pin every contact point with 1mm+ brass rod and two-part epoxy — CA alone won't hold long-term at this weight class. For kits with awkward footprints, build structural scenic elements and pin through those as hidden supports.

~86 cm² of playing surface — plenty for meaningful scenic work. The oval shape naturally suggests direction and movement, so use that to your advantage: build terrain that flows with the base's orientation. Elevation with cork, directional debris, or a trail behind the model all reinforce the sense of motion. Plan the composition around the model's facing so the base reads clearly at table distance.

3mm underside clearance fits 5×2mm or 5×3mm disc magnets comfortably. Use three or more spread in a triangle pattern — two towards the long ends, one at centre — for a balanced hold in transport. CA gel, check polarity before it sets.
