Work-life balance now extends to connectible and customised key rings

Chunky handfuls of keys can be easily lost or left behind. But what if you could easily and securely update your keys depending on what you were up to that day?

These nifty lego-inspired key ring connectors, designed by German designer Felix Grauer, allow you to create a different set of keys depending on your daily plans.

By building your key ring as you go, you can eliminate bulky extras.

What other everyday items could you make more manageable by building in detachable features?
