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.

Both outer dimensions match the 105×70mm nominal exactly — no undersizing, no oversize. The ~4mm total height and 1.53mm floor keep the profile stable under heavier monster and vehicle kits. 2.5mm of underside clearance fits 3×2mm disc magnets. Use three spread in a triangle pattern for a balanced, secure hold in transport.

105×70mm oval is a large oval base specification used in modern skirmish wargaming systems. Typically used for greater monsters, heavy warbeasts, large vehicles, and centrepiece creatures in games that use oval bases for directional facing.

Both outer dimensions match the 105×70mm nominal exactly. Correct for organised and competitive play in systems that specify a 105×70mm oval footprint. The oval shape gives a clear front-facing orientation for charge arcs and line of sight.

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. Dry completely before spraying.

At 105×70mm you're mounting heavier monsters and vehicles. Pin every contact point with 0.8–1mm brass rod and two-part epoxy — CA alone won't hold long-term for top-heavy multi-part kits. For models with small contact points, build structural scenic elements and pin through those as hidden supports.

2.5mm underside clearance fits 3×2mm disc magnets. Use three 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.

~58 cm² — enough surface for real scenic work. The oval shape naturally suggests movement and direction. Plan the composition around the model's pose: build terrain that flows with the base's orientation, add elevation with cork, and consider environmental detail that tells a story about the creature or vehicle. Keep the bevel edge clean for a tidy finish.
