AOS Nano Infusion Pen Tips - Refill

Finally, a refill pack that actually fits snugly — no more worrying about loose tips. The .25mm size delivers the same precise, gentle infusion as the original, and five in a pack means I’m set for a couple of months.

I was a bit worried about finding the right fit for my pen, but these .25mm tips snapped on seamlessly and the pack of five means I always have a fresh one ready. They feel firm yet gentle on the skin, which makes the whole treatment feel more hygienic and controlled.

The .25mm size is perfect for precise serum application, and having five refills means I’m never stuck with a dull tip mid-routine. I’ve already gone through two packs and the consistency hasn’t wavered once.
