Like I've mentioned before in a previous post, I've been bringing my secondhand Klean Kanteen when I go out for coffee. It's a little 12 ounce insulated stainless steel cup, covered in stickers from various shops I've been to, that I picked up for a couple bucks at a small town thrift store. It's nothing a normal person would get too excited over, but I've been over the moon about it since I bought it over a year ago because it's one of the best thrifted purchased I've ever made, and not just because they retail at like $25 new.
It keeps coffee hot for a long time. Like, painfully hot. An hour after filling it I still burn my mouth as long as the lid is closed. Most travel mugs I've had before would keep things reasonably warm for a little while, but this mug will keep coffee just about as hot as it was brewed for at least a few hours. The fact that it's like sipping molten lava for so long helps me pace my coffee drinking so I can enjoy one cup much longer.
Aside from coffee staying hotter longer, it also has saved me a little money-- not just from not having to freshen up my coffee when it gets cold. A lot of places, like Coffee Bean and Starbucks, historically have shaved off a few cents if you bring in a reusable cup, though I haven't been able to get a reusable cup filled for awhile now. I made back the $2 I spent on the cup pretty quickly in the 25 to 50 cents saved by having coffee shops forego the paper cup, so that was a win in my book.
Lastly, the environmental impact of cups steers my decision to use it. According to EarthDay.org, 16 billion disposable coffee cups are used every year, which is a lot of fucking cups. For a beverage that already has a not-so-great track record of sustainability, adding that many disposable cups into the waste stream makes things way worse. I've managed to avoid a few dozen cups and lids from getting thrown away by opting for my reusable cup instead of the disposable option. In the past year, I managed to keep at least a few plastic lids from entering the waste stream by transferring my coffee shop purchases from a lidless paper cup to the Klean Kanteen. It's a small step, sure, but I can at least do a little something to be nicer to the planet in those moments I find myself at a coffee house.
