At SKLUM we are committed to an original and versatile lunch box. There are many of us who usually have to eat outside the home, which means in most cases that we take the Tupperware to work. The 600 ml Birlek Bento Box Lunch Box is made of polyethylene , a durable and resistant material with beautiful colours, it will take care of keeping the food well preserved inside, since it closes hermetically. Take it wherever you want and you will succeed for sure! For proper maintenance , we recommend cleaning with a soft sponge and soap with a neutral pH . Not suitable for microwave and oven , they can be cleaned in the dishwasher.
