Need to add or update to your Aurora Tjet Track Pins and Locks/Connectors? Then this auction is for you! There are 200 brand new stainless steel pins and 100 brand new white nylon locks/connectors. I also have other listings with all black or mixed connectors. I ship these via USPS First Class Mail. If you order two of these, or If you order more than 1 item use the cart and you save on shipping. If the combined First Class shipping costs exceed the cost of Priority Mail, I will use that method for even faster receipt of items. Take a look at my feedback, these are high quality items that will help complete or upgrade your layouts. I also have auctions listed for larger or smaller quantities (at lower costs per unit - the more you buy the cheaper they get).
