Humbrol A3 Self-Sealing Cutting Mat for Plastic Model Kits

The Humbrol A3 Cutting Mat is a double-sided self-sealing cutting mat sized for plastic model kit building and sprue work.

About this model

One side carries scale markings for 1:72, 1:76, 1:32, 1:48 and 1:24 models alongside a 1cm square grid, so you can check part dimensions and keep cuts square while removing components from sprues. The reverse side gives angle markings at 30, 45, 72, 90 and 120 degrees for angled cuts and positioning parts during construction.

The self-sealing surface closes over minor knife marks as you work, which keeps the mat usable for longer and protects your blade edges compared with a hard cutting surface.

Common questions

What size is this cutting mat?

It is A3 size, giving enough working area for cutting parts from sprues or trimming larger components.

Can I use both sides of the mat?

Yes. One side has scale and grid markings for checking part sizes, while the other has angle markings for angled cuts and positioning.

Does the mat repair itself after cutting?

The surface is self-sealing, so minor cuts close up as you work, extending how long the mat stays usable.
