I can't wrap. I've tried again and again. I've shoved everything in as tight as I can and rolled the wrap over and shut but it always ends up a loose flappy mess. The folds on the ends open up and stuff starts dropping out and after a few bites it's more like I'm holding meat and salad in the centre of a big bread hankie. Does Lakeland have some kind of wrap roller/compressor? I feel like I'm failing the Twenty-Teens.
