Zaxy whale glitter jelly sandals - run small

EUC Zaxy Under the Sea clear jelly close toed sandals with silver glitter and adorable whale mascot. Size 6 US toddler (21 EU) but run a size small IMO. Worn around the house for a couple weeks before I had to admit they were too small. Daughter loved them, asked for them every morning. Very comfortable and soft with gel insoles. Priced to sell, bundle and save.
