The unusual and contemporary design creates a fairy tale of life beneath the waves. The sea floor has become a street where fish live in cute little houses, an octopus takes a ride on a bicycle, a seal has a piggy back from a blue whale and a killer whale carries her shopping home. Pieces are made with extra-thick, extra-durable cardboard, glare-free linen paper, and perfect, interlocking fit. No two pieces the same. The die-cutting tools are rebuilt manually by skilled tool makers after about every 60,000 puzzles produced. 100 Pieces. 6+ years.
