Question: So how do I open the bag?  I overstuffed it and need to remove items in order to move and store it easily.
Document: Living in a small 2 bedroom apartment, space has been always a problem for storing bulky items like winter beddings.I used to use XL Ziploc Big Bag Double Zipper. It was cheap, but it breaks easily, and the heavy duty plastic wasn't durable enough to survive 2 years. Plus, it doesn't make bulky items much smaller because they don't have vacuum technology. Though I tried with all my body parts to press them down as much as possible.
So disappointing! Every bag lasted about a month. The real bummer about this was that they were stored on closet shelves, and when the seals failed, they bulged up and I couldn't get them off the shelves because they were packed in so tightly. I had to cut the bags open just to get them off the shelf.
Bag tore immediately after putting in items. Waste of time and money. Not high quality material at all and seal is extremely sensitive and broke as soon as I tried to close
I travel a fair amount. For luggage use, its fine. The vacuum bags are good too. For the travel bags you'll get maybe 6-7 uses out of it. IF you only use it to pack and unpack. If you, like it, open it to grab a shirt, re-seal it, and do it all over again for the contents of the bag, yeah youll get a few (7) uses before you should look for a new one.
These bags are huge and holds not just pillows and blankets. I have placed my entire fall and winter sweater and other clothing items in two space bag cubes. I will do the same with my spring and summer clothing when fall comes. I'm very happy that they are reusable. They are great and worth every penny.
The capacity surprised me - I was able to put a TON of bedding in there (with room to spare!) and it compacted the entire pile down into a manageable cube. I would recommend putting the bag (full) inside the container you plan to store it in. This helps it shrink to the right shape / size. Otherwise, it will end up shrinking wide and flat - which is perfect for under the bed.
(Yes, I have the largest underbed bins. )So here come my new Jumbo space bags! At first, I had no idea how to use it. The instructions show pictures of a storage bin, but I didn't know what size of bins I need. I had no idea what size the space bag would shrink into. (-1 star) So I just put in a whole bunch of winter beddings, and vacuumed it without using a bin, and measured the dimensions.
This jumbo space bag compacted three blankets and four pillows with ease! The items that were once taking up a ton of space in our linen closet are now confined to a shelf. I'm impressed!
Works well and would recommend to friends. I would buy more whem I need them. Great productfor all to use
All clothes, linens, blankets and coats. I can store them in the barn with no worry of moisture or mold.
Answer: Push the locking mechanism to the opposite side of the bag and pull open the the top portion of the bag.  It will open similar to a zip lock bag.  I hope this helps.
