Tonfisk Design's Warm espresso cups enchant with a smooth combination of black porcelain and walnut. The stackable cups are dishwasher safe, and the removable wooden sleeve can be wiped with a damp cloth and oiled from time to time. The 2.71 fl oz (0,8 dl) cups are sold in a set of two. The Warm collection, designed by Brian Keaney from the Finnish ceramics brand Tonfisk Design, pairs porcelain with wood in a simple but stunning way. The Warm products are equipped with an oak or walnut sleeve, which protects hands from heat, insulates the hot beverage and gives the collection its characteristic, warm soul. The Warm tableware has become a modern classic of Finnish design, listed by the Wallpaper magazine in 2006 as one of the best designs of the decade.
