Does this SN seem legit?

[morimori]

I found someone selling it on a popular online shopping site in my country. It's one of the few ones available to buy here that aren't the pink curing salts.

It says it's "tech grade" with a 99% purity. Does that seem legitimate to you guys? Additionally, would getting the canister tub be better for its shelf life? I just want to know before I spend money and time waiting for it to arrive and testing it with blood.

Here are screenshots of the product page, I've blocked out the seller name and the shopping site's symbol.

It looks good. Definitely wanna test it with blood just in case though. Doesn't matter how you store it as long as it's air tight, then it'll last for decades.

Might not hurt to send a small amount off to a lab and get it tested for purity, also, as long as you can afford it (it's not that expensive0.
