We tend to see these on European sites, but right now the Moomin Homewares by Muurla are available from a UK site and even better, they are discounted at the Fab site.
Finnish designers Muurla have a range on offer featuring all the Moomins and their friends, including Sniff, Stinky and Little My. Specifically that's a range of mugs, plates and jugs, all with classic Moomins illustrations and all made of a tough (but fairly light) enamel-coated steel. Which means they're ideal for picnics and days out.
The discounted prices start at £9.50.
