I use the glue sticks often. They are useful at bingo and many other projects as well. Like the name says, they are wrinkle free which is important at bingo because it is very fast paced. Using the glue sticks helps me to keep my cards lined up neatly.
I keep a 3-Ring binder filled with blank copy paper divided by sections: DIY projects, recipes, etc. . When I go thru my magazines, I can quickly clip the page sections I want to keep, run the glue stick on the back and paste in the binder. The wrinkle-free formula really works great for the thin magazine pages and my pages lay flat.
The quality of this adhesive is VERY good. It gives strong, very strong, hold as soon as the envelope lid closes. However, the amount of glue in the tube is the reason why I rated this glue stick as 2 stars. Each tube is only ½ full and if you are using it for invoicing and other office mailings, you will find that it finishes fairly fast!
As for the smell, I do not find that it smells like rotting food. To me, it has a slight smell of alcohol- that's it. The scent is barely strong enough to smell it when open. You have to put it up to your nose in order to get that smell.
Anyways, the quality is good but it lacks the quantity.
