I also use the "Really Useful" 9ltr boxes (thanks Jerry) in various combinations , as a basic box , with the 15 compartment trays or the 7 compartment trays.
The 7 compartment trays are twice as deep (2 fit in a box) and the larger compartments are handy for 'outsize' items.(see photo)
Lots of sites selling them but prices vary a lot depending on :
1. How many you want.
2. With or without compartment trays.
3.
Postage !
Have just ordered 4 more 15 compartment trays , £2.50 each , VAT £2.65 and postage £3.25 = Total £15.90.
"Really Useful" site would have charged £11.99 for postage !
