Review on Tattoo Cartridge Needles, CINRA 100Pcs Tattoo Needles Mixed 3RL 5RL 7RL 9RL 5RS 7RS 9RS 7M1 9M1 5RM Round Liner Shader Magnum Tattoo Machine Needles #12 Standard Rotary Tattoo Needles For Tattoo Kit Tattoo Supplies by Charles Woods

Each cartridge is color coded so you can tell the difference between your round liners and magnum shaders. This is very helpful when switching between cartridges. However, the boxes aren’t labelled so you have to open each box to determine what kind of cartridges are inside. I recommend you label your boxes to make things more convenient for you in the future. Obviously, this isn’t the end of the world but it’s just extra work you have to do. The cartridges are transparent to provide better visibility and have wide windows for easy cleaning. However, the needle bar isn’t housed very tightly and it jiggles inside the cartridges. These cartridges aren’t the best quality but I think they’ll be good for practicing on fake skin.
