These are simple boxes for some things that need to be in one, like some paints, nail polishes or even some screws. There are 4 versions 9x12x4cm, 9x9x4cm, 9x12x6cm and 9x9x6cm. Please do not put food inside these because if printed with plastic that is not food safe (meaning it isn't safe to be in contact with food) it could lead to some health problems.
