Miles C. ★★★★★ Oct 22, 2026

The fit is perfect for my 20mm bases, and the MDF frame feels sturdy enough to survive tournament travel. I appreciate that you can pick the frame height to match your specific base thickness.

Sofia E. ★★★★★ Oct 21, 2026

Glued up in about five minutes and the fit is snug enough that my round bases don't wobble at all. Makes moving a unit of twelve skirmishers feel way more cohesive on the tabletop.

Daniel ★★★★★ Oct 20, 2026

The frame height option matched my 20mm bases exactly, so the models sit flush without any wobble. Assembly took about five minutes, and the MDF feels sturdy enough for repeated gaming sessions.
