Hand blown, this borosolicate glass manatee is made from cobalt glass with blue moon frit (tiny bits of glass). The manatee measures approximately 1-1/2" but please note that as each is hand made, sizes may vary and each piece may have a slight variance in colors. Yours will be completely unique, as no two are ever exactly alike. The pendant comes on an 18" black satin cord with barrel clasp (let me know if you need a longer or shorter cord) and in a gift box. Perfect gift for birthdays or other occasions.
