h2go soho 20-oz. water bottle
etsexpress.com, approx. $8 each (sold in bulk)

"The water bottle is a mainstay on every desk in our office. It travels well, making its way to many all-important conference-room meetings. The clear bottle reminds us when it's time to refill, keeping us hydrated and healthy throughout the day. [With] the wide-mouth opening, it easily transforms into a wine glass or beer mug for the late afternoon. Plus, it fits comfortably in my hand, making it the perfect accessory for gesturing while I'm talking with my team."

Folle 26 stapler
vintage

"Generally speaking, I don't like papers or memos. But it's even worse when they get unshuffled. The Folle stapler is a classic of Danish industrial design: simple, well-manufactured and enjoyable to use. It's made of stainless steel, hardened steel and iron, so it's serious. I've had mine since 1980, and it's still nicely satisfying to use--like the sound of German-engineered car doors closing."

La Marzocco Linea espresso machine
lamarzoccousa.com, starts at $6,800

"Not only does it keep the office fueled and going, it's also a social gathering spot where we compete for the best shots and discuss new product ideas. What I love about La Marzocco is that they've been building beautifully crafted products since 1927 and have a timeless appeal."
