Need to add or update to your Aurora Tjet Track Pins and Locks/Connectors? Then this sale 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 ormixed connectors. I ship these via USPS First Class Mail. If you order two of these, I will upgrade shipping to Priority mail, since the combined shipping costs for First Class is about the same. Take a look at my response, these are high quality items that will help complete or upgrade your layouts. I also have sales listed for larger or smaller quantities (at lower costs per unit - the more you buy the cheaper they get, and larger quantities come with free shipping).
