The shipping was fast. However, the bags are a little too wide for the vacuum sealer. I had to seal both sides first for them to work. After that, they are fineThese bags are great. Have used these all summer to freeze vegetables from the garden. Also use to portion size meat before freezing.Used both sizes with absolutely ZERO fail rate! Works better than the Name Brand or the off label I bought at Costco (those hit the trash) 1000% I’ve even used them to Seal over some Mylar LTS food packages that didn’t seal down for whatever reason. I simply popped a new oxygen absorber inside the Mylar, used my little trick (YouTube it) to vac seal it down and then quick sealed it up inside one of these and weeks later still nice and tight and my food safely put up for what ever us coming our way… hurricanes, food prices rising higher than mortgages or the next plandemic…The quality of these bags are awesome. Same quality as the actual Foodsaver bags but at a much reasonable price!!Easy and just as good as name brandWith food prices so high, I sure can't afford to waste any of it. The bags help me save money by making stored food last longer. Great price for the bags!Bags are too large for my vacuum sealer. Be sure to measure your sealer before purchasing these bags.UPDATE: I cut the bags down to size to fit my vacuum sealer and they do not seal at all. JUNK!!!Use them with the smooth side facing the heat sealer strip.Las bodas están bien , se ven de buena calidad y sellan muy bienBuen producto. Ligero y sencillo pero funcional.
