So what are they?
Basically they are solid oil paint in a stick. They have a cardboard outer wrapping that keeps you from getting messy and heal themselves to create a dry skin on the exposed surface after a few hours, so they don't dry out. You can use them on all kinds of media - canvas, paper, wood, plastic, metal, fabric... I use them on fabric and they are dry to the touch in 24 hours or less. Left for a few days they dry completely and can be made permanent by pressing with a hot iron.
Colors can be spread or blended with a brush or knife and a colorless blender allows you to make them less opaque. They are also completely compatible with any oil paints, although I have never done that. The makers claim that they are non-toxic and hypo-allergenic, and I have no reason to disagree.
If you want to try them out and not spend a lot - start with a sample size pack. Most of my varied collection are of the skinny and regular sized sticks - and to be truthful I don't think they will ever run out - a little goes a long way! I have one jumbo stick - and unless you are a serious user of oilsticks - I am not sure why you would ever buy one of these!
So how do you use them?
