Has multiple functions.
The brush is able to set to 3 positions.
1 brush in.
2 brush out
3 brush half way out.
On the other side there is a velvet piece on top of the pen to clean the mirror or lens.
There are two shapes, round and triangle shape.
The ball pump is nice. You can take the pin out and put it in the other way for smaller space. It should have had a bigger size on the other side so it would stick in the ball better. Now it just hangs in there, but that's fine for me.
The cloth is small but big enough for its purpose.
