Other than his brand-new fiancée Kaitlyn Bristowe, Shawn Booth has a few other mementos from his time on The Bachelorette.
"I kept all of the roses," Booth, 29, tells PEOPLE exclusively. "Every spot we went to and traveled to, I'd take them out and dry them out. I have nine of them!"
And the personal trainer's sentimentality isn't lost on his bride-to-be.
"We have this memory jar. And we both saved every little thing from our dates," says Bristowe, 30. "We have pictures, we saved every single thing, so now we have this jar full of memories."
And they're holding on to those memories – for now, at least.
"I want to sell [the final rose] on eBay," jokes Booth, to which Bristowe responds playfully, "That's not happening!"
