Complete guide: FK Irons Slim Xion 21mm Disposable Tattoo Grips
The FK Irons Gorilla Slim 21mm grip is a disposable grip designed specifically for the Spektra Xion machine, but compatible with any tattoo machine that has a drive bar with a 3mm center hole. The slim 21mm diameter offers a close grip to the needle, suitable for artists working precision styles such as fine-line, dotwork, geometric, or lettering. Being sterilized with ethylene oxide (EO) and individually packaged, it eliminates the need for in-house sterilization and reduces the risk of cross-contamination between clients.
How to use
- Check the sterile blister before opening — it must be intact, with no signs of damage.
- Open the packaging only at the time of use, on a disinfected work surface.
- Insert the needle cartridge into the grip's 3mm center hole.
- Adjust the needle depth using the ratchet disc system, between 0 and 4mm, depending on the desired technique.
- Mount the grip onto the Spektra Xion machine (or another machine compatible with a 3mm drive bar).
- Check that the cartridge is firmly secured, with no mechanical play, before starting work.
- Use the grooved area at the index finger for better support during work.
- At the end, dispose of the used grip directly into the medical waste container — do not reuse.
Tips from us
- The 21mm diameter is designed for maximum control, not for comfort during long shading sessions — if you alternate techniques, consider a thicker grip for shading phases.
- If you do not work with a Spektra Xion, confirm before ordering that your machine has a drive bar with a 3mm center hole.
- Store unopened grips in a dry place, away from direct light and high temperatures.
- Open each grip only immediately before use to avoid compromising the blister's sterility.
- Being disposable, do not attempt re-sterilization — the ratchet disc system and material are not designed for reuse.
Warning: Disposable grip, sterilized with ethylene oxide (EO) — use once on a single client, then dispose of as medical waste. Do not re-sterilize or reuse. Open the sterile packaging only immediately before the session and check the blister integrity — if damaged, do not use the product.
Frequently asked questions
Which tattoo machines is this grip compatible with?▾
It is designed specifically for the Spektra Xion, but the 3mm center hole makes it compatible with any other tattoo machine that has a drive bar of this diameter. If you don't have a Spektra Xion, check your machine's specifications for this detail before ordering.
How do I adjust the needle depth?▾
The grip has a one-piece ratchet disc locking system that allows depth adjustment between 0 and 4mm. The system prevents involuntary rotation of the disc even on heavier machines, so the setting remains stable throughout the session.
Can the grip be sterilized and reused?▾
No. It is a single-use product, factory sterilized with ethylene oxide (EO) and individually packaged. After use on one client, it is disposed of as medical waste — there is no recommended re-sterilization procedure for this type of material.
What tattoo styles is the 21mm diameter suitable for?▾
Being the slim version from the Gorilla range, it offers a closer grip to the needle than standard variants, suitable for precision styles — fine-line, dotwork, geometric, lettering. For long shading or color packing sessions, a larger diameter may provide additional palm comfort.
Why does the grip have a grooved pattern?▾
The grooved area is positioned at the index finger and provides additional support, useful for reducing hand fatigue during repetitive precision movements.
Why choose a disposable grip over a permanent one?▾
It completely eliminates the need for in-house sterilization between clients and reduces the risk of cross-contamination, being individually packaged and sterile from the factory — especially useful in high-volume studios or at conventions and guest spots where permanent sterilization equipment is not always available.
