Julian ★★★★★ Oct 22, 2026

The lower base sits perfectly flat, which was my main concern with these trays. Models slide in snugly and the frame height matches my 20mm bases exactly.

Penelope C. ★★★★★ Oct 21, 2026

I was worried about fitting my round-base models into ranked formations, but the MDF frame locks them in place perfectly. The base is solid and the height option I chose matches my 20mm bases exactly.

Abigail ★★★★★ Oct 20, 2026

The frame height options are spot-on—I picked the taller one for my 20mm bases and they sit flush without any wobble. Assembly took about two minutes, and the trays feel sturdy enough for repeated games.
