Query: Good blocks

I do not have the tools necessary to assess the degree of precision the these blocks meet, but I also do not require the degree of precision that they are likely to meet.These are good blocks.They help me with finer measurements as I learn woodworking.They are not marked. Anyone with at least one eye should not need markings on them to tell their thickness.Good blocks.
