Storage boxes for mounted figures armed with lances and spears

I store my figures in box files lined with magnetic sheet. These are perfect for most infantry and cavalry, but not deep enough for lance or spear armed figures on camels or horses, and some banner waving Mahdists on foot.

I found some fold-up box files on Amazon, which, at 310 mm x 260 mm x 140 mm, are plenty deep enough. The advantage of opening flat is the ease of getting figures out of storage and back again, minimising the risk of stabbing myself or, worse, bending a spear or lance.

A practical solution for storing figures which require more height, while reducing the risk of injury or, worse, bent spears, lances, or flag staffs.
