Por Vida LA Round Liner Tattoo Needle Cartridges

Precision. Control. Easy Identification. Made for the everyday artist.

Por Vida LA Round Liner Tattoo Needle Cartridges are designed to give tattoo artists a dependable, organized, and efficient setup from the moment the cartridge is opened.

Our cartridges feature the signature Por Vida LA red housing, combined with our color-coded membrane system to make it easier to distinguish Round Liners from Round Shaders, Straight Magnums, and Curved Magnums at a glance.

The individual cartridge packaging also features a pre-cut, easy-open design created to be easier to grab and handle during setup, helping keep your workflow quick, clean, and organized.

Round Liner Sizes

Available in:

1RL • 3RL • 5RL • 7RL • 9RL • 11RL • 13RL • 15RL 

Whether you’re working on extremely delicate details or strong, bold outlines, Por Vida LA gives you multiple size and gauge combinations to match your preferred technique.

Choose Your Gauge

The gauge refers to the diameter of each individual needle within the grouping.

Smaller-diameter needles are generally chosen for finer, more controlled linework, while larger-diameter needles provide a heavier ink delivery and are better suited for stronger, bolder lines.

#04 — 0.15 mm

Ultra Fine

Our smallest diameter option for artists looking for maximum precision.

Great for:

• Ultra-fine linework
• Tiny details
• Small lettering
• Intricate designs
• Delicate tattoos

This gauge provides a very fine contact point and more controlled ink delivery.

#06 — 0.20 mm

Extra Fine

A fine-diameter needle designed for detailed and precision-oriented tattooing.

Great for:

• Fine-line tattoos
• Detailed lettering
• Ornamental work
• Small designs
• Controlled linework

A great choice when you want fine lines without moving up to a standard needle diameter.

#08 — 0.25 mm

Fine / Versatile

A balance between fine precision and consistent ink delivery.

Great for:

• Fine-line work
• Script
• Detailed outlines
• Ornamental tattoos
• Smaller to medium designs

The 0.25 mm diameter gives artists versatility while maintaining a refined line.

#10 — 0.30 mm

Standard / All-Around

One of the most versatile diameters for everyday tattooing.

Great for:

• General linework
• Clean outlines
• Lettering
• Black & grey work
• A wide range of tattoo styles

The 0.30 mm diameter offers a strong balance between control, ink flow, and line definition.

#12 — 0.35 mm

Bold

Our largest needle diameter for artists looking for stronger ink delivery and more substantial lines.

Great for:

• Bold outlines
• Traditional tattooing
• Heavy linework
• Larger designs
• Strong, saturated lines

The larger diameter allows for a heavier, more pronounced line compared with our finer gauges.

6.5 mm Extra Long Taper

Every Por Vida LA Round Liner cartridge uses our preferred 6.5 mm Extra Long Taper.

Instead of offering multiple taper lengths, we chose one consistent extra-long taper across our Round Liner collection to provide artists with a predictable feel from one configuration to another.

Why 6.5 mm?

An extra-long taper gradually narrows toward the needle point, giving the artist a more refined contact area.

This makes it especially well suited for:

• Precise line placement
• Detailed tattooing
• Fine-line work
• Controlled needle contact
• Clean and consistent outlines

The different gauges determine how fine or bold the needle performs, while the consistent 6.5 mm taper maintains the precision-focused characteristics of the Por Vida LA Round Liner collection.

Instead of changing both the gauge and taper, artists can select the needle diameter that works for their style while keeping a familiar taper throughout the lineup.
