All in one microblading pens like this one can make every procedure much simpler. They come with microblades already inserted into the handle and the entire product is sterilised. These come in a few different sizes, depending on your need and preference, but all come as straight handles with a finger grip for more control. They weigh ~7g and are about 135mm long.
This handle contains a 5 pin round shading microblade. Each microblading pen is individually sterilised and comes with a lid or cap to prevent bending of the needles during transport.
