The color makes it easy to see where the glue is and if you need more elsewhere. Great for my toddler who is learning how to apply glue to construction paper or other craft projects. The quality is good the paper projects stick well and even foam crafts stick well and do not fall off easily. Nicer then traditional glue because young children tend to use too much and the project doesn't dry quickly enough...she wants to play with her crafts right away so this glue makes it possible. An added bonus is the fun purple color I like it because it is different but it is great for my daughter as well.
The caps of the tubes seem hard to remove or to replace compared to other brands. Fighting with the caps on a glue stick shouldn't be a concern but the glue quality itself is fine for everyday use.
I use the glue sticks primarily for sealing envelopes. They work better than messy sponges or water. However I don't find them that strong. Once the glue dries it's easy enough to open the envelopes or anything else the glue stick was used for.
