Will the outside not be hot with a cup without a handle?<!--en-->No. Melamine conducts heat poorly, so the outside wall stays cooler than with porcelain. The ribbing also keeps your fingertips away from the smooth surface. This is precisely the same property that makes the cup pleasant to hold. However, this does mean that the cup itself does not keep the coffee warm; preheating helps.<!--en--><!--en-->Is melamine safe to drink from daily?<!--en-->Melamine is a common material for tableware and is approved for food contact, provided you use it for its intended purpose: cold and hot drinks, no microwave, no oven, no highly acidic liquids left in it for hours. Overheating is the only real concern, and you avoid that by not using the cup as cookware.<!--en--><!--en-->Does it scratch from a spoon?<!--en-->Melamine is harder than most plastics, but softer than glaze. Stirring with a metal spoon can eventually cause fine lines. <!--en--><!--en-->Is melamine safe for daily use for drinking?<!--en-->Yes. Melamine dinnerware may only be sold in the EU if it has been tested for migration and complies with regulations for food contact materials; furthermore, melamine from China is subject to additional controls with mandatory test reports at the border. The material is naturally BPA-free — BPA belongs to polycarbonate and is not present here. Please note for this cup and saucer: no microwave and no oven. Not because of a health claim, but because melamine damages the material itself when overheated, and that is the only situation in which something goes wrong.<!--en--><!--en-->Why melamine and not porcelain?<!--en-->On a boat, at the coast, or in the garden, you don't want shards. The same applies at the campsite and around the pool: shards on a tiled floor where people walk barefoot are not an inconvenience but a problem. Melamine is less prone to breaking than porcelain, and if it does break, you don't run the risk of it shattering into thousands of pieces on the floor of your cabin or pool.
