the glue is VOC free, with a synthetic rubber as a basis. you kind of get the feel of speed glue, but actually, just kidding, you do not!!
it is very easy to use. comes in a little bottle, squirt some on your rubber and blade, and spread it with the sponges that come with it. the thing i like about this glue compared to others is that it dries very fast and nice. i think this and butterfly fre chack are exact same things: packaging si teh same, texture, smell, feel, etc. you have to be careful thou, the glue builds up very fast. it helps if you mix a little water when you glue with it.
