Mini Waterpas Sleutelhanger

I clipped this onto my keys and it's already saved me from hanging a crooked picture frame. The blue color is subtle enough that it doesn't scream "tool" on my keychain. Works exactly as a tiny level should.

The neon yellow is way easier to spot in my bag than I expected, and the little bubble moves nice and smooth when I check picture frames at flea markets. It's already saved me from hanging three crooked shelves this week, which is three more than I caught before.

Clipped it to my keys the day it arrived and already caught a crooked picture frame in my hallway. The blue casing feels sturdy enough for daily pocket carry, and the bubble settles quickly so I’m not squinting forever. Small thing, but honestly it’s the most useful trinket I’ve bought this year.
