Baby Twins in Box

Double Trouble with newborn twins. They cozy up together in their box to go to sleep and keep their mum on her toes during the day. One of the twins has a polka dot onesie with a lace collar while the other has a striped onesie with a lace collar. 

The little details: The box is made of cardboard and measures 4.5" by 3.2" by 2" - Mice are just over 3" tall.
