Buyers in order for you to have a pleasant shopping experience, pay attention to the following points before purchase:

1. optical axis is a cut piece, so do not accept returns outside the quality issues, please know oh. 2!

2. Because we are using a cutting machine roughly according to the size of the cut, the general error within 10MM (only long, not short), shorter than 100MM can not be cut. If you need the exact length, please be careful to shoot Oh!

3. Optical shaft is the whole (2 meters or 3 meters) clamped at both ends of the plating, so the top two ends may have plating layer is too thin, blackening and other phenomena. Cut pieces if you can not accept one end of the possible existence of blackening, please inform the buyer message! Otherwise, we will default delivery.
