N gauge foam storage? Ten Commandments supply difficulties

[jamespetts]

For years, I have successfully used the Ten Commandments N gauge foam storage slots with 4l Really Useful boxes (2x 9 slots can fit in one box) for my N gauge rolling stock.

However, Ten Commandments have been out of this for a long time, and, on e-mailing the proprietor, I now understand that the person who does the cutting may retire and that these may no longer be available.

Does anyone know of any good alternatives for a 4l Really Useful Box?

Look on ebay and amazon for foam block with pre-cut cubes that you remove to create suitable slots.

I bought this a few months ago
