William Y. ★★★★★ Oct 21, 2026

The upper frame slides snugly over the lower base with zero wobble, which keeps my round-based units perfectly lined up in formation.

Thomas ★★★★★ Oct 20, 2026

Assembling these was straightforward, and the frame height I chose holds my 20mm round bases perfectly snug. No wobble, and they rank up just like square bases now—exactly what I needed for my warhammer unit. It feels solid and well-made for the price.

Mia Z. ★★★★★ Oct 19, 2026

I was worried my round bases would wobble in a ranked formation, but these trays lock them in perfectly thanks to the snug upper frame. The MDF is sturdy enough for gaming without being overly heavy, and the two-piece design makes assembly straightforward. Exactly what I needed for my fantasy army.
