Zoe ★★★★★ Oct 20, 2026

The 20mm round bases fit perfectly into this tray's slots, making rank-and-file movement much smoother. I chose the taller frame height and it holds them securely without any wobble. Really pleased with how clean my table looks now.

Richard ★★★★★ Oct 19, 2026

The two-piece design is clever — the upper frame holds my round bases rock-solid while the lower base slides smoothly across the table. Sizing the frame height to my bases took a minute, but once matched, everything lines up perfectly for ranked formation.

The fit is perfectly snug for my 20mm round bases, and the two-piece MDF design makes it easy to swap different units in and out. I was worried the frame would be too loose, but it holds everything securely during movement.
