I'm in the US and I got one off Amazon. There are at least 3 sellers selling them. This is the one I got mine from: https://www.amazon.com/gp/product/B07YB7NJQ4/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
The original was MINKPINK (and not emerald green), but there are a lot of dupes online, including on Amazon. Just be careful of sizing because they're usually out of China.
