Many thanks for the useful addresses.
Could I ask the previous authors to check if the lids are PVC (polyvinyl chloride which will age to an unpleasantly sticky material giving off hydrochloric acid) or acetate ? The Walsall Box Company mentions acetate lids for its presentation boxes.
I wouldn't recommend using any storage items which contained PVC.
Many thanks
