Dinosaurs mobile. This Dino mobile was inspired by a little 4 year old boy who loves dinosaurs, so we said why not make one just with those scary creatures. Mobile turned out beautiful, the little boy loved it so much that he jumped around it and screamed: me, me me... Dinosaurs... Great buy for a boy as toddle room decor over his bed or play area. Any dinosaurs lover would appreciate the colorful colors and classic Dino shapes. Custom colors are welcomed, please message me with details. Mobile Base: Cross base color is customizable to match crib color: black, white, natural wood, or brown. Please mention the color of the base in the note section if listing has no option to choose a color. Material used: Pieces made with premium cardstock and are die cuts glued together in two or three layers depending on the shape and glued to the 8lb fishing line that is tightened to the base. Dimensions: Mobile hangs about 36 inches down (from the hanging ring down to the last crystal) size may slightly differ due to the handmade nature of the mobile. The hanging strip is approximately 18 inch the rest is the mobile itself if crystals attach to the bottom it will add an extra inch in length. The hanging strip made for one size but if you need it longer you can Easley remove it and attach to a longer strip. Mobile base has a little ring by which you can hang it. Mobile base is cross shaped and is 12 inch in diameter. Please let me know if you have more questions on the dimensions, but I hope I covered it all in here.
