This card uses the soon to arrive, Rustic Harvest Suite. You'll find the products in the new July Through December 2022 Mini Catalog. It's available to purchase Starting July 1st.
I think the name is Slider Flap Fold Card.
The front scalloped layer slides off the card to open it up. There are two scalloped die cuts (second largest) adhered back to back together using a strip of 3/8" foam adhesive or the bottom strip of the dimensional sheet. It's applied across the middle of the back scalloped layer. It its slid through the middle opening of the card front.
