Review on 100 Pcs Heavy Duty Vacuum Sealer Bags - 4 X 6 Inch, Smell Proof, Boilsafe, And Freezable, Commercial Grade For Airtight Food Storage And Sous Vide by Bob Collins

Poor quality and inconsistent sizing and mil thickness! Typical Made in China product! If you chose these bags for the size to store items that fit perfectly within the bag, bad idea! Besides the fact that internal usable size is way smaller than originally declared 4 x 6 inches, these bags do not have any consistency in size or mil thickness. Expect a surprise with every order. Seams on edges vary from order to order, anywhere from 0.125" to 0.375", while external bag size remains unchanged. This makes a big difference in remaming usable internal space, considering how small this bag is!
