Question: What size is each stick?
Document: It work great, I wish is longer, Costco's size big is much bigger then this , I have to use two stick to lock it.
They are a tiny bit hard to use until you get used to them but they do a much better job than clips or ties.I like them a lot.
These are the best things ever. Have used every type of chip clip and only these truly work. Not sure how or why, but they do!
These are the best thing since sliced bread ---- Most of mine are in use at all times, but STORAGE space is minimal and those other 'pinch-n-clip' things are impossible to store. I wish I'd been the inventor of these!! !
These are so easy to use. Can't get enough of them. No freezer burn on my veggies. Chips stay fresh
These are incredible! they really work and are easy to use!Only improvement I would make: Make a larger bore one for thicker packaging (such as goldfish cracker bags)
These Gripstic are so convenient and airtight vs. regular chip clips in closing cereal packages, pretzels and the like. Having 3 sizes to use makes them even more convenient. Highly recommend and have given to family to get them hooked as well!
It is so hard to slide the &#34;Gripstics&#34; over the bags that it's a hassle. I cannot do it easily, nor can my children. The only way I have found to make it work is to repeatedly fold the bag over and crease it. Then you can slide the &#34;gripstic&#34; over the bag. But that is way more effort than just using a chip clip.
It is really quite easy to hold bags of chips, bagged salad, etc closed with this product. It takes a try or two to learn how to attach this, but once you get it, it is really easy to use. Seems to keep contents fresh.
I've ordered gripstics before and they had the gripstic logo on them. These ones were very flimsy and had no logo. I don't think they are going to last. I feel a bit cheated, why dont they have the logo on if they are the genuine product?
Answer: The green one is 11 inches, Orange is 8 1/2 & the purple is 7". The green one is good for lgr potato chip bags. The purple is good for crackers that have the smallers bags in the box. Plus I use them for my bagged coffee. I found them in a grocery store & bought two sets. I gave my son a set and a friend also ordered them online. Then went back to the store to get more & they were gone. I love them I just wished I would have thought to invent these.
