This is a particularly cute little box. Awhile back I bought up a bunch of these to use as gifts. The seat lifts up to reveal that you have a spare tire and a pink half-shell in case you need them ; ) The only source I’ve found for them is a regular eBay seller. They’re listed as “marybdecorativeart” or you can search with the words “scooter trinket box.” They’re $12, including shipping with the US.
