The Perfect Small Tape Measure: The Ti-Tape is simply the world's smallest titanium tape measure. Slightly larger than a US Quarter, it is the perfect tiny tape measure for everyday carry. With 3' of measuring capability, it’s ultraportable, durable, and lightweight. Removable Keychain Clip: Customize your pocket tape measure with the included modular keychain clip. Attach it to your keys or carry it discreetly in your coin pocket for easy access. User-replaceable Mini Measuring Tape: What happens if your measuring tape gets worn or bent? Not a problem! The user-replaceable design allows you to easily change it out for a fresh tape that is ready for action! Blue Raspberry Anodized Finish: The color-shifting Blue Raspberry finish must be seen to be believed. As the retractable tape measure moves around, colors shift from blue, to purple, back to blue. Dimensions: 31.5 mm [1.24"] diameter, 9.70 mm [.38"] thickness (without the keychain attachment clip), and weighing only 21 grams [0.74 oz].
