Hobby Heaven 100mm round plain bases are flat, unslotted bases for gargantuan monsters, the biggest vehicles and war machines, and major display centrepieces. They are injection-moulded from matte black ABS with a fine adhesion texture across the top face. This subtle grain helps paint, glue and basing materials grip without adding a fixed scenic pattern. As the largest common round format, it suits enormous creatures, large flying models, super-heavy machines and diorama subjects that need a broad, stable foundation.
Flat, unslotted design with no raised lip.
Fine top texture supports painted and scenic finishes.
Suitable for gargantuan creatures, vehicles and war machines.
Useful for major tabletop and diorama centrepieces.
Compatible with popular tabletop miniatures; not affiliated with, endorsed by or produced by Games Workshop.

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.

Customers praised these plastic bases as "perfect for miniatures" with "top quality" at an "excellent value" price point. Shoppers found them ideal for basing large-sized minis. One reviewer noted they're slightly thinner than premium alternatives, which may affect heavy models, but overall "aesthetically perfect" with fast delivery.

Great Value
Comparible to GW bases for a fraction of the price. Seems to be slightly thinner construction but shouldn't be an issue unless you are planning on putting a heavy model centrally on the base. Aesthetically perfect.

Hi
I'm trying to put an order in,but when I go to pay,PayPal are claiming I may have to pay £45 in import taxes,is this correct?
(I'm in UK btw,so not sure why it's coming up)
Hobby Heaven
Hi. If you are in the UK then there is no chance that you will pay customs duty and import tax - we are a UK based company. It's probably just an automated message from paypal that everyone receives
