I have no way to test it, so item is sold as-is. Box has some wear and dust. I get lots of e-mail from people asking questions that are fully answered on the page.
I uses shipping calculator - if enter the incorrect weight or dimension, difference could be significant.
Do not even think about asking me to declare it as a or the value of an item less than sale price.
This offer is for one nos ballast resistor tube. I try to charge only actual shipping cost. I don't pack boxes in advance to get exact weights because offer combined shipping.
While I am happy to accommodate such requests, they add size and weight the package increase shipping cost. Most of the items I sell have been in storage or houses for many years and as a result may odors, such mildew, mold smoke.
I am not an expert on the items sell.
I have made and do make mistakes.
