5. f,l,o,w,e,r,s ruler by Studio Note. "The flower ruler is probably the most beautiful and poetic pieces we have in our shop. In the spring, the artist, Norihiko Terayama, picks flowers for the ruler, dries them, meticulously places them in one-centimeter increments and casts the flowers in acrylic. They are only available to order in the spring when the flowers are in bloom."
