I’ll begin by admitting that this is not the easiest thing to remember. I was diligent all last July and I always had my glass jar with me in my giant tote bag, along with the already mentioned glass straws, bamboo utensils, etc. But now I often find myself out and about with nothing - I haven’t carried my giant tote with me since moving the Boston. It’s freeing, but it also means I don’t have my things that help me stay plastic free.
But - this is one of the best things you can do in the summer when you know you’ll be buying iced drinks - like tea, coffee, or smoothies. I personally use the jars leftover after I’ve finished my coconut oil from Trader Joes.
