I bought a few sets of these a while back. They come packed in a team bag and all look the same, so it's hard to tell if they were hand packed or not.
The bag has a sticker on the front with a bar code and says:
X001ZHEXKV
Jasion Stickers Food US
Made in China
A Google search shows that they make a bunch of different sticker varieties. I think it's how they got COVID-19 into the US.
