Everything that was once cool will be cool again. This isn’t just some unfounded cliche, it’s a completely true statement. For a bit of a retro vibe when it comes to desk accessories, check out this nostalgic Braun Calculator. Based on Dieter Rams’ classic design from 1987, this ET66 reissue is the source of inspiration for your iPhone’s calculator app. While you can use your computer or all the apps you want to solve your mathematical issues, there is something sharp about having this guy on your desk. The calculator comes with a protective slide cover and of course the quintessential Braun minimalist style you’ve come to recognize.
