Extreme version, the Extra Stark version, and the Loose version, but this is the first time I've had the regular strength version. If you're new to snus, one thing you'll come to realize is that there aren't many lime flavored products on the market. There's basically the ones Odens makes, and then there's a nicotine pouch version, Lyft Lime. So this is a rarity in the snus world! The flavor description for this one says, "A normal strength portion with a taste of lime". Each can weighs 20g and has 20 portions, for 1g each! The nicotine content is 9mg/g (0.9%), for 9mg/portion.
