Hey doll customizers and crafters! This 20-piece rooting tool set is exactly what you need for giving your dolls amazing new hairstyles. You get two different sizes - 10 pieces of 0.6mm (0.024 inch) needles and 10 pieces of 0.8mm (0.031 inch) needles, perfect for different doll sizes. The smaller 0.6mm needles work great for smaller dolls with heads from 0.79 to 1.57 inches, while the larger 0.8mm needles are ideal for bigger doll heads. The metal construction is durable and these tools are seriously easy to use - just put hair on the doll's head, hook the hair with the needle facing toward it, insert into the doll's skin, pull out, and repeat. It's way simpler than it sounds! These aren't just for rerooting hair either - they're fantastic for hair styling and all kinds of doll customization projects. The quality is noticeable right away - these don't feel cheap or flimsy like some doll tools can. If you're into doll restoration, custom doll making, or just want to give your existing dolls a hair makeover, this 20-piece set gives you everything you need to create beautiful, shiny hair that makes your dolls look absolutely charming. It's one of those specialized tools that seems intimidating at first but becomes super satisfying once you get the hang of it!
