TATTOO TIPS FOR BEGINNERS Round liner (marked RL) tattoo needles are used to make lines and details since they are packed tightly. Round magnums needles (marked RM) are used for shading and color fill. Compared with weaved magnum needles or flat needles, round magnums conform better to the skin, giving a more consistent line, better ink dispersion, and doing less skin damage. Please do not tattoo on human skin if you are not a professional tattoo artist. You may hurt yourself. If you still want to tattoo on real skin, you had better buy professional tattoo ink which can stick to the skin better than the ones in the kit Notice: This tattoo kit is only for use by adults. Without guardian permission, children and teenagers are not allowed to buy tattoo equipment.
