Using this Passage Cutlery Set is super easy. You can use the knife for cutting and the spork for scooping and spearing your food. When you're done using it and need to move around, just snap the handles together. If you want a longer spork, connect the handles in opposite directions. As for maintenance, you can wash it with mild dish soap and warm water. Make sure to dry it thoroughly to keep it in good condition. Since it's made of EU food - grade glass - reinforced polypropylene, it's safe for your food, but avoid using it on extremely hard surfaces to prevent any damage.
