In real life, the Rhino's horns are made of keratin, which is the same type of protein that makes up hair and fingernails. However, this unique Rhino's "horn" is made using a Phillips screwdriver head, while the rest of the Rhino is handcrafted, using recycled nuts, and bolts. This cute Rhino makes a wonderful gift, especially if you are a lover of animals of any kind, or keep one for yourself. :) May not be suitable for small children. SIZE: 2.5" Width x 6" Length x 2.5" Height Dimensions are approximate. As with most items made using recycled materials, there are some imperfections. HANDMADE IN THE USA
