Your review: Never in my entire career have I seen such uniformity in a product. All 1000 of the bags were exactly the same size. each seam was perfectly straight. The labels were uniformly placed and easy to locate on the front (or back if you turned them over) of each bag. The closures were perfectly placed at the top of each bag, making filling the bags especially easy. I am sure that using these bags will be the delight of my day.
