Brand new. I bought 2 of these so my kids could buckle themselves. (The booster seats were too bulky and made it hard to buckle the regular belt.) It has been a complete game changer for us, but my daughters new booster was less bulky and doesnt require an extender. This definitely works for a toyota highlander. I'm assuming it should work for other toyotas as well. From a non smoking, pet free home.
