FUNNEX® Coffeemaker

Took this to the office and brewed straight into the mug — the 5 to 15 oz range is perfect for my morning cup, and the silicone gasket keeps everything snug in my bag. The borosilicate glass feels solid, not flimsy like other portable brewers I've tried.

The double-walled glass keeps the coffee hot without burning my hand, which is perfect for my morning commute. I’ve used it for both a quick 6-ounce cup and a full 15-ounce refill, and the silicone gasket makes it leak-proof in my bag. Exactly what I needed for travel.

The double-walled glass keeps my coffee hot way longer than my old mug, and the silicone gasket makes it leak-proof enough to toss in my bag. Brewing straight into the 15-ounce mark is perfect for my morning commute, and it’s sturdy enough that I don’t baby it.
