Handy and versatile
discovered these at my brother's, got them to "gift" me a few, after trying at home I knew I wanted the entire assortment. Biggest problem after finding the web site was deciding how many of each size, I even got some handles, knowing from the gift they would fit birdseed bags.
The big "secret" is the crease. You must get a good crease with no wrinkles or overlaps; by doing that I am able to use them on many, many types of bags -- cereal, chips, pancake mixes, even sugar. The crease can be tricky on some things the first time you try, but if you manage the secret it will work. I'm a true believer.
Also, after I decided what I wanted ordering was pretty easy. Order servicing was outstanding; I had them nearly cross-country in under a week with free shipping. At the beginning of COVID-19 shutdown.
