LINDEN SWEDEN Twixit Mega Bag Clip - Keep Food Fresh, Prevent Spillage - Great for Storage and Organization - Microwave, Freezer and Dishwasher-Safe - BPA-Free, Black

this thing is a piece of junk, and it's too small. I see several other reviews saying this "works perfectly" for big bags of pet food. I'm using it for a 10 pound bag of cat food and even that is proving to be a struggle. I've only just started using it and I've already seen it snap off the package by itself due to being unable to stand the pressure. and this clip is most definitely not even close to air tight. you have to fold the bag in order to fit the clip and not let out any air. it is better than using multiple small clips, but it's not a clean solution. unfortunately there doesn't seem to be a product out there that is capable of doing such a simple job so I guess this will have to do, but I'm absolutely not happy about it.

sturdy clip that securely closes large bags of bird and squirrel food, tab makes for easy enough opening

We use it to close a 15 lb heavy plastic bag of dog food. Sometimes we get a 10 lb bag, it works for that too. I'm pretty sure it would work on a larger bag. It's strong and closes securely. It releases by pressing a button/ latch on the end. Having hand strength issues, sometimes I can't squeeze a spring loaded 'chip clip' type, but this is always very easy. It comes in a few colors, I just got red because it was the cheapest by several dollars.If you want air tight or need to keep ants out, put your dog's food in an air tight container. This does close tightly, but it's just for closing the bag. The brands we buy have micro perforations or tiny punched holes in the bag, so air tight is not going to happen with any clip.We've used Twixits for, gosh, over twenty years I think. My mom got some in a big jar at an organizing store and they still work great, except for the ones that have wandered away over the years. We've both gotten the new fresh colors, her original ones were primary colors. I wish this big clip had been available in something like lime green. This big one is a different construction, it's hard plastic with an actual hinge, but still the same concept.Two things to note:1. It is huge, as long as your foot or a big baby's arm. I knew the dimensions of it and was still a bit taken aback when I opened the box.2. See the black wavy piece in the middle? That is the ingenious part! It's removable! It's held in by the pressure of the wavy design. If you have a larger bag or have trouble closing it, just pull that piece out. To pop it back in, just push the waves as needed to get it back in, it's like a gentle spring. I tend to clip a corner of the bag, so even on a larger bag I often leave the wave in. The only problem is that the wavy piece on all colors of this clip is black, I so wish it was a bright color because I know it will get lost if I don't tuck it on the shelf next to the dog food.

This item is not long enough to use with a large dog bag. When the edges of the dog food bag are folded over, the opening of the clip is not wide enough to secure the top of the bag.

I purchased one of these large bag clips many years ago at Petsmart. It really, easily sealed our large pet food bags after they were opened. It lasted about ten years! I wanted some more, so I researched Amazon and found them! I ordered two more and I have them sealing two large pet food bags! I will probably order some more soon, as I really do recommend them.

These work great on resealing a 25lb bag of beans for short term storage. Maybe not so great for long term food storage. I’d buy these again.

I bought this for bags of pet food which were too large for regular clips. It works really well and I highly recommend it. You can find it cheaper in other places, perhaps, but it lasts a long time so the convenience of Amazon outweighed price concerns.

After reading the (mostly) rave reviews about this clip I ordered it and was hopeful it would do the trick. It did not. I hated it. If I fold the small 5lb bag flap over too much the clip wouldn't stay closed and would fly open and fall off. If I folded the bag over so it wasn't as thick the clip would slide right off. Annoying. Someone had pointed out the shortcomings of this clip in another review but said they had solved it by putting a bamboo skewer inside the clip. When I did this the stupid clip wouldn't even close. Maybe I just got a defective one but I absolutely hated this clip. I will use a cannister, a food grade bucket or a giant rubber band. This clip was terrible.
