These 2 guides are meant to work in conjunction of larger width strips in completing a wider bead but they can be used by themselves to make tiny seed type beads. 
The picture shows both sides of the 2 laminated cutting guides.

You can get these two laminated cutting, guides as a set at Amazon.com.

Although, the cutting guides are accurate, I cannot guarantee perfect results with any of these cutting guides.
