The ToolKid hairpins have been specially designed for the nail holder. They serve as a clamp system to keep the nail straight up and in its place. They are easy to attach into the nail holder and to replace.
There are regular hairpins for sale, but they come in many different sizes. That is why we developed the special ToolKid hairpins for the nail holder, which always fit perfectly. This is, most of all, important when aiming the nail (keeping it straight up and providing sufficient clamping force). The ToolKid hairpins are also made of stronger material, so they last longer.Download the user manual here
