50 Lakeland Strong Foil Sheets 5 "So Useful" Miss Doig 28 December 2017 I have bought this item many times and would never be without a few packs in my Cupboard. I agree it is certainly useful for securing Sandwiches and small left-overs in the Fridge. However, I swear by it for another purpose: lining Roasting Pans for anything and everything. The handy size fits so neatly and not only saves money in the long run, but aids with the washing up. Excellent product and vfm.
