Lot of 2 connectors. These are custom made pieces that are wooden train track compatible and close to identical to the original wood versions. They are sturdy and made of ABS plastic like Lego Brand uses. My sons use some with their wooden train track sets and they fit the standard sets like brio, Thomas the train, kid kraft etc and they have held up well. 

(The other tracks in the photos are not for sale and were used for scale and so buyers can see the fit, you are only getting the two connector pieces if you bid.)
