10 stars!
Color: black, Color: black
These gift bags are on another level! The card stock is heavy duty and the quality is out of this world. Your guest will love anything inside this bag. The tassel and tiger tag is so unique and makes this extra special. It’s a medium sized bag and can hold a good amount of stuff. I would love to see these in different colors as well. Truly a wonderful gift bag!
