Design

They are the perfect size for my mini bundt cakes. I really love that the cardboard bottom is already in the bags so I don't have to assemble them. Not sure how small the cupcakes are in their ad picture, but my silicone bundt cake form measures 4 inches so my cakes are a little smaller than the bag. Could not be happier! I would definitely recommend.

The bags are a great size and quality. I love the cardboard on the bottom for a little added stability. I would buy these again and recommend them to others.

We were very pleased to see the thickness of the cellophane was good. Also, it was nice to see the cardboard bottom. We often use these to put out chocolate covered oreo cookies in. whatever treats we put in it will look great.
