Hi all
you know those flat metal 'Tradesman's' cases you get of screws etc - with several plastic 'sub-trays' of different colours and interlocking sizes. for the different sized fasteners?

Any idea where I could get sets of (cheap) replacement sub-trays? I have only found them costing several pounds per tray, even on eBay. There must be someone who sells a knock-off variant. I have a couple of empty cases I want to fill...

Thanks
