WooCommerce, manually add a product and price for purchase

I’m trying to figure out if there’s a way to use the WooCommerce Cart and Checkout functionality if I need to purchase something that isn’t technically a product

In other words, it’s a completely independent “membership” that needs to be purchased, but isn’t a product post.

I’d love to be able to add an item in the cart manually … manual name, manual price, manual meta data and then purchase.

Does anyone have any idea how to do this?
