I use this product to create and send invitations postcard thank yous and sale reminders to my customers. It is great because it is the perfect size for the photo tray on my printer.
I bought these to print invitations to a holiday event. It's much cheaper to print on these 4x6 cards than to take to the copy shop and have color copies made on cardstock and then cut to size. It's also easier to align the front to the back. There's plenty of room for the information and I've even included maps on the opposite side and still have room for an address for mailing!
I used these in Culinary school to write my recipe cards for each class! They are very convenient for keeping my recipes in order and hold up extremely well during a long day of cooking!
