The difference is in the way (mounted together or not) the posters arrive to your customers.
Framed Poster: posters and frames come as two items packaged separately within one package. Your customers need to assemble it.
Ready-to-Hang: posters are placed within frames. Your customers can hang it directly on the wall when receiving it.
Tip: You can always find more information about our products in the Product Catalogue section of the Gelato Dashboard.
