Special Note:
Custom engraving requires time, and any delay in shipping due to this reason will not be the responsibility of the seller. Orders with custom engraving for which there are no quality issues are not eligible for returns or exchanges. By placing an order, the buyer agrees to waive any liability of the seller. If you are concerned about this, please think carefully before making a purchase.
Please be advised that the product performance parameters and product size parameters are based on internal self-tests at the factory and may have slight errors. Please understand and forgive.
