Lucy F. ★★★★★ Oct 22, 2026

I was a bit skeptical about MDF holding up, but the upper frame and lower base fit together perfectly and feel sturdy. These trays let me finally use my round-based minis in a ranked formation without them wobbling.

Thomas ★★★★★ Oct 21, 2026

Finally an option that doesn't require magnet drilling—the frame just slides snugly over my 20mm bases. The separate base and upper frame means I can mix round and square in the same unit.

Harper ★★★★★ Oct 20, 2026

Used these to swap my round-based units for ranked play and the MDF frame slots onto the base with barely any wobble. The height option I picked matches my 20mm bases perfectly, so no fiddly gaps. Solid upgrade for anyone tired of loose movement trays.
