This is truly a unique assortment of tattoo needle cartridges, and I've never seen anything quite like it. There are sixty cartridges in this set, and of those there are 12 styles and sizes. That breaks down to 5 cartridges of each type.
I guess you could rightly call this set a "sampler".
Included in this set are 1201RL, 1203RL, 1205RL, 1207RL, 1209RL, 1205RS, 1207RS, 1209RS, 1205RM, 1207RM, 1209RM, and finally 1215RM. So that gives you 25 round liners, and 35 shaders, or two types (Round Shader, and Round Magnum).
You'll notice all of these cartridges are build around the number 12 needle, which is thicker (at 0.35mm) with a shorter (2mm) taper. That makes them stout, and tough.
The cartridges are well made, with medical grade plastic body in a yellow tint. You can't see it, but there are internal stiffeners for additional rigidity.
There is a large port/window just above the well & tip. At the top there is a silicone plug, and internally there is a silicone diaphragm that prevents ink from traveling up to the pen, and also provides rebound.
These are all factory sterilized, then placed in sealed individual blister packs. On the reverse you'll find all pertinent info, such as date of expiration, lot number, and size/style.
These are nice looking cartridges, and a truly great set. Perfect for beginner, or pro, these are a very good value.

It came as pictured, I haven’t used them yet so I gave it a 4/5. Looks like basic tattoo cart. Not fancy, not crappy either.

Love the look. These seem to be great quality.

These have worked so far with any of my various branded tattoo pens that I use these kinds of cartridges with! Definitely some nice little disposable needles! Very precious and worked well on the client I used them on. Very easy to recommend these!

Great product for the money doesn’t shade well but nice crisp outline
