Love making your own bobblehead dolls or shaking toys? This CHGCRAFT kit has everything you need to get started! It includes 24 spring bases in 6 different sizes, ranging from about 15x11mm to 60x20mm, so you can choose the right one for your project. The springs are made from stainless steel-colored metal, so they're sturdy, have good elasticity, and won't rust or fade easily. Each base comes with self-adhesive tape on the bottom, making it super easy to attach to a doll head, car dashboard, or any other surface. The tape is strong but removable, so you can adjust or reuse the springs without leaving permanent residue. Just give a little tap, and the spring wobbles or nods – perfect for creating fun, animated crafts. Great for DIY enthusiasts, model makers, or anyone who wants to add a moving element to their creations. Use them for custom bobbleheads, dashboard toys, jewelry, or even as quirky gifts. Let your imagination run wild with this versatile spring kit!
