I don't like use shelving racks, "IKEA KALLAX" etc. for my records/singles/cds, I prefer individual plastic boxes, IMO gives more protection that anything. The "Really Useful Boxes" catch my attention, I like that have a flat floor and looks like have squared side, my actuals have rounded sides, not flat flood and not solid, I'm looking a replacement. WEBSITE: Go Shopping - Really Useful Boxes - Music & Film » 12 inch: the problem! that I see on the picture is almost NO space on the sides, so if by example the record have outer sleeve is possible that don't fit for 7 inch looks better more space on sides. for CD's looks good. someone has try this boxes? do you recommend it? thanks.
