Sebastian H. ★★★★★ Oct 22, 2026

Finally! A tray that actually fits my 40mm round bases without any wobble – the snug channel on the lower base holds them perfectly. Used it for my heavy infantry unit and it slid into rank smoothly.

Joshua ★★★★★ Oct 21, 2026

Glued these together in about 10 minutes and they hold my 40mm round bases perfectly in ranked formation—no wobble at all. The height option was exactly what I needed to match the base thickness.

Sophia C. ★★★★★ Oct 20, 2026

The upper frame fits my 40mm round bases snugly without any wobble, and the MDF material feels sturdy enough for repeated game use. I glued mine together in about five minutes, and they’re already holding a full unit perfectly on the table.
