Masayuki Kurokawa (1937) is an award winning architect and product designer, whose work has won numerous honors worldwide. Traditionally, salt and pepper shakers have one hole for pepper and three holes for salt and the container is usually opaque so the contents inside can not be seen. Mr. Kurokawas concept behind the Balloon Shakers was so you can see what's inside the shaker as it can be used for not only salt and pepper, but all kinds of seasonings. Hand-blown by Shotoku Glass Co., who originally created lightbulbs in Japan, therefore creating a very thin (yet durable) glass balloon. Available at Merchant4.
