"Sending these out this week! January can't come soon enough," Luyendyk captioned the post.
Burnham marveled over the save the dates in a video on Instagram Stories.
"Our wedding invitations are here!" she said. "They are so beautiful. They did a great job. They even printed the labels on there for us."
Luyendyk and Burnham will tie the knot Jan. 12 at Haiku Mill in Maui, Hawaii. The couple gushed about their upcoming nuptials in an interview with "The View" in May.
"It's not your typical beach wedding. It's so pretty," Luyendyk said of the venue. "It's a private wedding, so not on TV."
