Like other Passage series products, this set is made of EU food grade glass reinforced polypropylene. The handles feature contact points that enable packing all three parts into a stack. In the bowl (720 ml), the curve between the base and sides has the same exact radius as Sea to Summit spoons, ladles and spatulas. This makes it effortless to scoop every last drop or crumb of your food off the plate. The mug's lid, complete with a drinking hole, helps keep your drink warm and protects it from bugs, pine needles etc. The measuring scale on the inside is a highly practical feature for an outdoor or camp cook - you're always carrying a measuring cup when you've got your Passage cup with you. The knife is sharp enough for cutting, but also wide enough to use as a spreader. Passage product family products are a great choice for hikers, bike tourers, for camping and why not summer cabin use. - Lifetime guarantee against flaws in materials and manufacture - Hand or machine wash - BPA-f
