Wait, really? I definitely buy them sometimes (not the pictured ones, the purple one, habanero ... something flavor?) and I know I checked ingredients. Did I really miss eggs? That seems unlikely, but I'll have to check carefully next time I see them.
Well, hopefully I live somewhere where the noodles do not have eggs! I'll definitely read the ingredients again next time. It would be super sad if I couldn't eat them anymore, because they are delicious, in a painful kind of way
For everyone who is vegan who sees this (all 3 or so of you), it's fine! I have not accidentally eaten eggs, there are no eggs in the version that I can buy here, I'm attaching a photo of the ingredients for you to check for yourselves.
I went out to a few stores, and did some internet research. Found a mail conversation with samyang on a Swedish forum. According to them none of their noodles sold abroad contains meat, fish, eggs or diary production. The egg noodles are supposed to just be domestic. However, a lot of my local Asian food stores carry Samyang products with eggs, probably obtained through a Korean re-seller rather than Samyang themselves.
Here's the ingredients of the (vegan) 2x that I just bought:
tl;dr: it's probably vegan, but you should still check the ingredients.
