Genuine FoodSaver rolls of vacuum sealer bags. They're normally $39 for 2 rolls which is a rip off. I've tried Kmart versions and not a fan and always had to double seal them. Haven't been game to try the generic brands on Amazon but Wevac seems to be well rated but since the minimum length at 28cm is 45m, it was a bit much.
Expired 2 x 2 rolls for $44.99
BPA free and sous vide friendly.. bought four rolls. thanks
