Tubes are test good for emissions with no shorts or leaks   Testing: we test all tubes using the following testers: KNIGHT KG-600 Picture:  When we sell one tube, we may show a picture with multiple tubes. In that case, we are showing you the variety of the brands or boxes available for that one tube. If you would like a particular brand, please contact us to request it *before* making your bid. If not requested, we will select a brand at random. Boxes:  If we do not list the original boxes and do not show the condition of the boxes, then you may get your item either in an original box or in a generic white box (if a box is specified in the listing). Attention collectors! Please ask us about the box condition before the bid, if it's unclear. If the box condition is not specified, it means we may send you the tube in soft packaging, without a box. We guarantee safe shipping. Shipping: For United states buyers: we ship exclusively via USPS. We combine shipping on similar items from other listings. If you buy items from multiple listings, hold payment until we send you an invoice with shipping and handling discounts. Shipping: For international buyers: we ship all our items from New York. We ship items up to 4 lbs using USPS International Mail. Items over 4 lbs, we ship using USPS Priority Mail (as per USPS requirements).  Every package has an individual customs number, which you can see in your buying record, and is proof of shipment.  If you'd like to use a different carrier, please contact us for a quote. You are responsible for any customs and border fees levied by your country. Payment:  Please, PAYPAL only.  If you made a bid by mistake, please tell us as soon as possible, so we can cancel the transaction. Payment, for US residents: if your shipping address is in NY state, you must pay sales tax, which is calculated on the entire total, *including* shipping and handling charges, as per NY state law. If you are a reseller with a certificate of authority, we will remove the sales tax from the invoice upon seeing your resale forms.   Thanks for your interest and Good Luck Bidding.If you have any questions or dont see listing you need let me know !!!!!
