Assembly needs some force + optional felt for surface
You WILL NEED SOME FORCE to clip the numbers in the mounts, but they fit perfectly and the game will be super strong. I suggest smoothening the edges of the numbers with a lighter a little before inserting them. Worked good for me.
And note that the numbers have a FRONT and BACK, so make sure to insert them the right way around!
In order to dampen the sound of the dice I suggest using some self-adhesive felt (e.g. from eBay, your local hardware store, ...). The inner width of the box is 210 mm which is exactly the width of DIN A4 format.
