Every cartridge from Kwadron is a true synonym for precision, sharpness, which allows you to create detail and detail unattainable by other cartridge manufacturers. Cartridges in size 0.30 (#10) are sometimes referred to as Double Zeros because of the notation e.g. 1003, where 10 is the needle size and 03 is the number of needles in the cartridge. A size popular in all tattoo styles and techniques due to its versatility. The flow of ink with 0.30 mm (#10) needles is still even and controlled, allowing the creation of great detail, but not as restricted and slow as with 0.25 (#08) size needles which are more tightly soldered.<\/p>\n<\/div>\n\t\t\t\t\t\t\t\t\t\t\n\t\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t<div class=\"box\">\n\t\t\t<div class=\"image\">\n\t\t\t\t<img decoding=\"async\" src=\"https:\/\/kwadronpmu.com\/wp-content\/uploads\/2025\/05\/kwadron-cartridge-system-025mm-rl-round-liner-1szt.jpg\" \/>\n\t\t\t<\/div>\n\t\t\t<div class=\"desc\">\n\t\t\t\t<div class=\"description\">\n\t\t\t\t\t<p class=\"product-description__title h1\"><strong>Kwadron RL cartridge types in 0.35 mm size<\/strong><\/p>\n<div class=\"product-description__desc\">\n<p>Kwadron cartridges in size 0.35 (#12) are available in 12 versions, depending on the number of needles you find in the cartridge.
