The Grimm's Building Set Rainbow Lion from Oskar's Wooden Ark is a wonderful building set in a wooden frame that combines organic shapes in oiled natural wood and colourful geometric shapes. The Majestic Building Set is more than a tribute to an endangered animal. With this set, we wish to bring a little HAKUNA MATATA into your life. The saying originates from the African Swahili language and means "There is no difficulty" or Do not worry".
