These bags have triangular sides (gusseted) so they will expand to hold more contents. They will sit flat if you have items inside that are weighted or will sit up by themselves. This size bag is great for regular size coffee mug with product in it, 1-3 product delivery and remember to tie it with a bow to make your customers feel special. Bags are also food safe. Our Satin Ribbon Thank You in Pink/Gold, Black/Gold or White/Gold makes a great combination.
