Another business party sets that available at my store is Spa business. I have 7 cliparts design and 3 background colors. They are available in 10 different products: invitation, business card, gift certificate, appointment card, flyer, paper plate, paper napkins, banner, stickers and labels. Did you know that you can transfer the design into a product that you want by yourself? If you don't know how, check this post.
Total 6 posters. Check them here.
These just an example, they are more at store.
