I purchased these as my daughters' birthday is coming up and we are doing a rainbow unicorn theme. My intention is to use the emoji and small heart molds to shape candies in different colors for our guests. The other molds I am sure that I will use over time as my daughters love Hello Kitty, animals and hearts, so the whole package together was a really good deal. I love that these are silicone versus metal as they are easy to pop out once cooled, and can be quickly cleaned, dried, and stored in the bag that they came in. They don't require any kind of sprays or oil to ensure that they come out of the mold easily, and the molds won't rust or stain.
