Zipper Vacuum Seal Pouches by Vesta Precision | Clear and Flat Vacuum Sealer Bags | With Zipper and Valve | Designed for Handheld Vacuum Sealers | 11 x 16 inches | 15 Vacuum Bags per Box

After years of using vacuum bags, I have found these bags hold up the best. The valve doesn't fail like the brands with the blue valves. I have not found a source for just the replacement valves with out buying more bags. These bags are not only thicker, but the ziplock is much more secure. They are also harder to zip but they provide a slider that assists nicely with the task.

Good product

Estás bolsas funcionan bien pero solo por unos cuantos minutos, después el aire entre como una bolsa normal, probé con más de una y con diferentes cosas (pan, fruta..) y el resultado es el mismo. Las fotos que anexo muestran unas rebanadas de pan segundos después de haber sacado el aire, y la misma bolsa después de un par de horas (el aire ya había entrado)

I use these with my sous vide set up. They'll hold a 2" thick Porterhouse and maintain the vacuum while frozen. The Vesta handheld vacuum pump is more powerful but I'd love a counter-top vac sealer that would also accommodate these bags.

These bags did not work, they let air straight back in
