Great Bags!
Set name: 20 Combo
The bags are perfect for packing clothes for storage. I used them for my babies clothes and they fit great. I love the variety of sizes, and they are very easy to use. The zipper piece is a bit tricky to get on, but the zipper stays locked in place when closed.

Saves space and keeps moisture and bugs out
Set name: 20 Combo
I have never bought these bags before. I went with good reviews. I used to pack my extra curtains in them. I definitely saved a lot of space. I tried using the hand pump, works fine just more effort and time on my part. The sweeper works fast and great. These are awesome bags. Ordered another box.

Vacuum sealer bag with pump
Set name: 10 Jumbo
The storage bags are a nice size fit a lot of blankets and comforters with no problem and I have a lot of them. The problem I have is the pump they give you is ridiculous. Would take you forever to get all the air out. I use the vacuum hose and it’s still took some time but a lot easier than the pump they give you that’s why I gave a three stars instead of five.

Multiple size bags and easy to use.
Set name: 20 Combo
I was pleasantly surprised with how great these were. I chose these for the variety in bag size but I thought I would forever be using the hand pump. Very surprised it worked very quickly and the suction held. Would definitely recommend!
