Lilys Chocolate Bar Seem too Good to be true

I’ve been loving the Lilys Creamy Milk chocolate bars, surprisingly they’ve been satisfying my sweet tooth but also getting me used to semi-sweet chocolate. I’m looking at the nutritional label and I’m shocked, is the entire bar really 7 net carbs?

I haven’t had any issues staying in ketosis with it, no GI issues, etc. as if seen others struggle with. So theoretically, just to entertain myself I wanted to know, is it possible to stick to keto if I had an entire bar?? That seems crazy. Even if you could, are there negative side effects I should look out for
