Found at Kmart Forster, these Anko 1.18L Tumblers are now on clearance for just $5. They were $15 once upon a time so that’s a pretty solid markdown.
It’s a big tumbler too, 1.18L means fewer refills, and it’s double wall stainless steel so it keeps drinks cold for ages. A lot of people say it holds up well compared to more expensive brands, which makes the $5 tag even sweeter.
