Exactly what i needed.
These metal sheets are great for transporting your minis safely
Works perfectly
Had to modify my plates as they didn’t quite fit my 4.1L boxes? Maybe a US-UK differential problem. Still got them to work, but the lack of actual dimensions published in the description made this a problem that could’ve been easily avoided. They absolutely work as advertised otherwise!
A bit pricey for tin sheets but when you don't have a supplier these are perfect
