The International School Flea market is to be held on 8th May from 9 a.m. to 1 p.m.. This is a really good place to pick up foreign language books and toys and also electrical equipment and sports goods. Many ex-pat families move out of Finland at the end of the school year and sell up a ton of stuff before they go.
