How do I store konjac noodles??

So I’m probably insane and bought almost 3kg (the liquid it floats in not included) of konjac noodles and rice and I’m wondering how to store them. Each pack is 250g noodles so I probably won’t eat it all at once, how long can I store the opened bag in the fridge? And how to store the unopened ones?

Also how often can I eat it bcuz I’ve heard you can’t eat those everyday

Also you can drop your fave konjac rice and noodles recipes here I’d appreciate that
