Three tools in one compact gauge. Measure needle sizes from 2–10 mm (US 0–15), check stitch/row gauge with the built‑in ruler window, and tidy ends using the integrated yarn cutter. Clear metric/US markings make swatching and needle identification effortless between projects. A practical notion for everyday kits, classes, and travel—durable, easy to read, and sized to slip into any pouch.
