T9, S5, and K7 share a built-in battery, metal handle, and bayonet cartridge fitting, but their controls and cartridge choices differ. For a distributor or private-label buyer, the useful comparison is which configuration fits the planned product range, refill inventory, and retail kit.
The table below compares the specifications on MOOKARDILANE’s current product pages. Use it to prepare a shortlist, then confirm the exact finish, cartridge series, and packing list on a sample and written quotation.

The adjustment ranges describe the devices’ specifications; they are not instructions for choosing a treatment depth. Battery duration is the catalog’s “up to” figure, rather than a comparative test result. Confirm packaging dimensions and weight again if the kit or box changes.
Compare the appearance before choosing a finish



How to build a procurement shortlist
T9 Golden and T9 Grey provide six speed levels with a display listing both speed and charge. Put T9 on the shortlist when those controls match the configuration in your brief. The published specifications alone do not establish a performance advantage over the other families.
S5 Blue and S5 Gold list six levels and the wider adjustment range. S5 is also the only one of these families with 7705 listed alongside 7701 and 7704. If an existing refill range uses 7705, that is a concrete reason to investigate S5 and verify the pair on a sample.
K7 Pink and K7 Black list five levels and an LED display for speed and battery. Compare a physical sample when the control layout or finish matters to the range. A lower count of speed levels does not by itself demonstrate lower quality.
Confirm the kit, not just the pen
All six finish pages list the same packing components: pen, two round nano cartridges, charger adapter, USB charging cable, and instruction manual. The cartridge series still needs to be named. “Two nano cartridges” does not identify the fitting, option group, or exact refill SKU.
- Write the pen family, finish, quantity, and plug option as separate fields.
- Name the cartridge series and exact tip option, with the number included per kit.
- Confirm the adapter, cable, manual version, and proposed box on the sample.
- Keep photos of the approved controls, finish, and complete packing layout.
- Compare quotations using the same kit contents; obtain project-specific pricing and schedule.
Use the 7701, 7704, and 7705 compatibility guide to define consumables, then place the shortlist in the first-order OEM brief. Keep the approved configuration with the records described in the sample and repeat-order guide so a later purchase can refer to the same model and kit.
