This set of 3 snack containers is great for adults and kids. Simple downward pressure on the lid to close and a twist-and-lift motion to open it- even the young kids can manage! The containers nest neatly with their lids, so you'll have beautifully organized storage container drawers too. Approx sizes Small 7.5 cm diameter x 4.5 cm tall, medium: 8.5 cm diameter x 5 cm tall, large: 9.5 cm diameter x 5.5 cm tall.
