My absolute favorite whale are the distinctive sirens of the sea, the Humpback Whale. These whales are gorgeous creatures with their beautiful whale songs and hunting using a technique called bubble netting, which I've associated with the planetary orbits. The name of this pin is, "Sea Siren" featuring a humpback whale with a bubble net and orbital design along its body. This is a lavender purple pin with dark purple glitter accents. This hard enamel pin is 2.75" in length, is set on a highly-polished gold-plated metal and has two posts on the back. THE FEATURES - Highly polished gold-plated metal. - 2.75″ hard enamel pin. - Has two posts on the back to secure the pin and prevent rotation during wear.
