This is a mini mobile that can be attached to a stroller or car seat. It has been opened, but is unused. It can be attached with one touch. The dinosaur mascot makes a squeaking sound when you press its belly. The blue fluffy part in the center makes a rattling sound when it sways. The dinosaur egg has a soft, fluffy texture. The green leaves are teethers. This mobile can be hand-washed, so I think it's safe in terms of hygiene. Thank you for looking.
