Quadratischer Schlüsselanhänger mit Maßband

I was pleasantly surprised by how compact this is — the 5x5cm square fits perfectly on my keychain without adding bulk. The retractable tape measure pulls out smoothly and locks in place, which makes measuring small items around the house way easier than I expected.

It's a simple idea, but having a tape measure clipped to my keys has come in handy way more often than I expected—measuring a new shelf spot just today. The whole thing is barely bigger than a matchbox, so it doesn't add any bulk to my pocket.

The retractable tape measure clicks back smoothly every time, and at 25 grams it disappears into my bag without adding bulk. I’ve used it twice already for quick furniture measurements, and the compact square shape is way more practical than those round ones.
