I also find the Lidl ones to be quite good and better than the mission ones which I find crack and rip too easily. No doubt a consequence of making something with such a long self life. I used to work in a Mexican restaurant with wraps being the main focus. Ours were bought in but fresh on a daily basis and they were substantially better, also they were larger than the Lidl or Mission ones which I assume are 10" and even though only 1" or 2" additional on diameter made wrapping a decent sized burrito so much easier. I quite like the parcel method or the open one end, foil helps keep the parcel that but is a faff for home and egg wash sealing also works if you get the frying pan out. I do mean to make my own at some point, it is disappointing how hard it is to get lime slaked corn though in the UK no major supermarkets stock it as far as I'm aware.
