Thank you for viewing! Empty milk cartons, set of 10. Sturdy, about as thick as cardboard. I hope you can use them for making toys at school festivals or in childcare. Just cut and fold the top to quickly turn them into cars! ↑ Cars are not included. *Size: 16.5 x 13 x 8 cm (Size when assembled) *When shipping, I will fold them flat and ship them in a simple manner. Thank you for your understanding.
