Decorate your own squishy and get an easy to carry clear plastic box to transport it in while it dries. You buy the base squishy which includes some basic supplies but you can add extras for additional cost. The directions are simple and in English. It takes around 30 minutes. You make reservations online in their system. The ladies were very friendly and welcoming and helped even our 9 year old create an artfully decorated squishy that she was thrilled with. It was a fun experience for kids but made a great Tokyo souvenir. Appropriate for any age but would be especially fun for a family with children.
