Testimonials

I’d say Airfix Model World is the best on the market. Well laid out, well written and plenty of diversity. Definitely the magazine the others strive to beat

Tim H

Key Model World A ‘one stop shop’ for all things model related.

Cleverly designed and unique laser-cut kits which have made my layout stand out from the crowd.
