A round liner is the configuration most studios buy first, so this index starts there. The MOLONG MO Round Liner is a soft-membrane family of cartridge needles built on a finger ledge, and it is broken down below across the five axes that decide a purchase: net diameter, needle-group size, membrane, machine fit and box packing. It is written for studio owners, senior artists and distributors who need to compare tattoo needles by configuration rather than by headline claim — and every row of the matrix leads to the same purchasable variant page.
This range ships as a pre-packaged, sterilized cartridge rather than a loose needle bar: the needle group sits inside an integrated housing with a soft safety membrane, the grip section is rubberised for anti-slip control, and every unit is sealed in its own blister. Because the unit is pre-assembled and pre-sterilized, cartridge loading and clean-up take less time than assembling a needle and tube separately — which is why the page is organised as a configuration index rather than a tutorial.
Read it in one direction: the orientation block below tells you what is inside a box, the matrix answers "which configuration exists", the ladder shows every threshold at a glance, and the final modules cover the machine side, the packing side and the commercial side of the same order.
Every row is a selectable size inside the same round liner family. Diameter and size are two separate dropdowns on the product page, so both values have to be chosen before the item can be added to cart.
| Size | Diameter options | Cartridge style | Safety membrane | Box quantity | |
|---|---|---|---|---|---|
| 1RL | #06 0.20mm / #08 0.25mm / #10 0.30mm / #12 0.35mm | Finger ledge, ergonomic rubber grip | Soft membrane | 20 pcs | |

Two rails, one page. The diameter rail shows the four net sizes listed for this family; the size rail shows every round liner group you can select. Nothing on either rail changes the membrane, the packaging or the box count — those stay constant.
This rail is orientation only — the buying decision is made in the matrix above and completed in the two dropdowns on the product page.
Four common buying situations, each tied to one axis on the product page and to one concrete next step. Start from the scenario that matches your studio and follow the axis it points to.
Axis to set Needle-group size and net diameter
The product page positions this round liner family for intricate designs and detailed work, and pairs the soft membrane with a finger ledge for smoother glide and steadier ink flow. That makes the size and diameter dropdowns the two decisions that carry the most weight here.
What the page lists 1RL through 18RL, across #06 0.20mm, #08 0.25mm, #10 0.30mm and #12 0.35mm
Choose size and diameter on the product pageAxis to set Machine and grip fit
The range is stated as compatible with all universal sizes of tattoo machines, and the cartridge body carries a finger ledge plus an ergonomic rubber grip for anti-slip control during long sessions. Confirm your own grip or pen before you commit a box to the shelf.
What the page lists Universal fit; integrated housing for stability and reduced vibration
Work through the machine-fit checklistAxis to set Membrane and sterilization
The soft safety membrane keeps the needle stable and prevents ink backflow, and each cartridge is 100% EO gas sterilized and individually blister packed. If your studio protocol puts cross-contamination control first, this is the axis to verify before quantity.
What the page lists Soft membrane, EO gas sterilization, individual blisters
Read the membrane and safety breakdownAxis to set Box count and commercial path
Each box holds 20 pieces, and the product page supports wholesale and bulk purchase wording. Mixed-size orders are simply multiple boxes of the same line item, so build the quantity list by size first and price it second.

Send a quantity list for a wholesale quoteThree layers of the same cartridge decide how safe and how stable it feels in the hand. Each is described on the product page, and each one changes what you should look at when comparing a cheaper alternative.
Keeps the needle stable and prevents ink backflow, according to the product page. Inside a cartridge housing the membrane sits between the needle group and the ink path, so the buyer decision is whether backflow protection is part of your standard setup.
Buyer verdict: make it a baseline requirement, not an upgrade.
The cartridge body includes a finger ledge and an ergonomic rubber grip for anti-slip control, and the integrated design is described as seamless for stability and reduced vibration. That combination is aimed at extended sessions rather than short passes.
Buyer verdict: check the ledge against your grip style before ordering boxes.
Every cartridge is 100% EO gas sterilized and individually packaged with blisters, which is what keeps the safety claim intact all the way to the chair. A pre-packaged, sterilized cartridge also shortens setup and cleanup time.
Buyer verdict: never buy cartridges that arrive without intact individual packaging.
This module is about what physically arrives, which is what distributors and stockroom managers need to confirm before placing a quantity order.
Leave each cartridge in its sealed blister until the moment of use, keep boxes in a dry place away from direct sunlight, and inspect the blister before opening — a compromised seal is the one condition that cancels the sterilization claim. Rotate older boxes to the front of the shelf so nothing sits unopened behind newer delivery.
Because every size shares the same 20-piece box, quantity planning is simple arithmetic: pick your sizes, then multiply by boxes. The product page currently displays a $0.00 – $12.00 price range across variants; volume terms sit outside that display and are handled through the quote path.
| Order size | Pieces | Typical buyer | Price basis | |
|---|---|---|---|---|
| 1 box | 20 pcs | Single artist trialling a size or diameter | Variant pricing shown on the product page ($0.00 – $12.00 range displayed) | |
| 5 boxes | 100 pcs | Working studio restocking common sizes | Same variant pricing; ask about volume terms for repeat orders | |
| 10 boxes | 200 pcs | Multi-artist studio across several sizes | Volume pricing on request | |
| 20+ boxes | 400+ pcs | Distributor or reseller stock order | Volume pricing on request |
Mixed-family and mixed-size orders are quoted fastest when the request states each size, each diameter and the box count per line. For customization, OEM/ODM or bulk-order terms, use the same contact route.
