I have about 50 of these. Widths vary between 8.5cm and 10cm. Light pine plywood
These were Ikea Knuff (see https://www.ikea.com/gb/en/p/knuff-magazine-file-set-of-2-fibreboard-20562513/) but as said plywood rather than the fibreboard Ikea now use.
Collect from Royston (unless you want them all at which point I might be persuaded to deliver if it helps)
