Ross Stik is a glue stick that is photo safe, non-toxic, and washable. It can be used for putting photos in albums and also for craft projects.
The application is very simple. You just take off the cap, turn the base to bring up the glue stick and apply with firm strokes. Always remember to replace the cap or the glue will dry out. It isn't messy at all to use. This glue is also acid-free. It gives you a very smooth application, and the stick comes in a handy tube that is small enough to carry with you if need be. It does not have a strong odor and works OK for the most part.
Unfortunately, I have found that in certain cases it didn't really keep things in place as well as other glues I have used. I like the fact that it is so easy to use and also non-toxic and acid-free, but I don't always get the sticking power out of this glue that I would like.
If you are doing something relatively simple, this glue would probably work fine. But if you want something that will last over time, I would advise using a different type of glue.
