4 Assorted Pack-Mate® Vacuum Bags 2 "Easy to use" Miss Appleyard 27 February 2018 Excited to try these out. We were pleased with the results initially... I bought two packs. It significantly reduced a duvet and sleeping bag and fitted neatly in a pine trunk. As we were sucking air from the second bag we noticed the first filling out again. It was the first time it had been used. Maybe just a faulty bag as the seal was still closed. Meant to have 5 year guarantee. A note from the team Yes, you clearly received a faulty bag. We see we were able to replace this when you contacted us about this.
