A derma roller or stamp specification needs more than a needle count. The count identifies the model, while needle length or adjustment range, material, head structure, finish, and packaging identify the configuration being quoted. Keeping these fields separate helps a buyer compare samples and avoid receiving the right model in the wrong variant.
MOOKARDILANE lists 540, 180, and 192 needle rollers, plus 169 and 141 needle stamps. The comparisons below describe catalog specifications for procurement. They do not prescribe treatment depths or establish which model produces better clinical results.

The ten listed lengths are 0.20, 0.25, 0.30, 0.50, 0.75, 1.00, 1.50, 2.00, 2.50, and 3.00 mm. Write the selected length on each roller SKU. The 13 cm dimension describes the tool’s length, not its needle length.
The 540 Roller and 180 Roller offer two listed needle materials, while the 192 Roller lists stainless steel. Do not transfer a material option from one model to another. Where several colors are available, ask for the current color reference and approve the selected finish on a sample.
169 vs 141 stamp specifications
| Specification | 169 Stamp | 141 Stamp |
|---|---|---|
| Needle count / head shape | 169 / hexagonal | 141 / round |
| Needle material | Stainless steel | Stainless steel |

| Handle material | ABS | ABS |
| Listed finishes | White; Black | White; Black |
| Protection / unit pack | Protective cap / individual printed box | Protective cap / individual printed box |
The 169 White Stamp and 141 White Stamp differ in needle count and head shape. The same dial range does not make them one SKU. Record the count and finish, including 169 Black or 141 Black when selected.
Use product photos to check model identity
Turn specifications into clear order lines
Give each combination of model, length, material, and color its own SKU and quantity. An illustrative roller line is “540 Roller; 0.50 mm; stainless steel; color reference to confirm; crystal case and paper box; quantity to confirm.” The length here is an example of a catalog option, not a recommendation for use.
A stamp line can read “141 Stamp; White; protective cap; individual printed box; quantity to confirm.” Record the published dial range on the attached specification sheet. If rollers or stamps are packed with a pen, list the number of each component per kit and provide a packing layout; a shared carton should not erase their separate model identities.
- Match the model and count on the quotation, sample, and packing list.
- Confirm the roller’s selected needle length and needle material.
- Confirm the stamp’s head shape, dial marking, cap, and finish.
- Approve the unit case or box, artwork, labels, and kit quantities.
- Keep dated sample photos and written configuration approval for reorders.
Common specification questions
Does a higher needle count mean a longer needle?
No. Count and length are separate attributes. The roller catalog offers the same ten lengths across all three counts.
Is a stamp dial range the same as a roller length option?
No. A roller order selects a listed needle length; a stamp is listed with an adjustable dial range. Record the relevant specification for each format without converting it into treatment advice.
Include these fields in the first-order OEM brief. For pen refills, use the separate cartridge compatibility guide; cartridge series numbers do not replace roller or stamp model counts.
