Description is ok. Shipping very fast !
The holders have drilled holes to fix the tools. The hole has a diameter of 4.44 mm. It does not depend on the screw. See pic. It is still too small. The shop did not accept the tolerance problem. The tool to insert has a diameter of 4.7 mm. So the tool can not be used. It is a matter of poor manufacturing tolerance. The diameter of the lenstool is too much. It should be less than 4.4 mm. I wanted a replcement or a refund for that useless product. The seller has rejectedby now. So I am not satisfied with the product.
