YES! Since lollipops are basically just large sugar crystals, they can lose their shape when exposed to humidity and heat. Also, my lollipops are made with simple ingredients and none of the funky preserveratives you find in store-bought hard candies, as such, any "shapelessness" that you experience is the natural process of sugar. They may not be pretty, but they still are delicious. It is always recommended to keep them in a cool, dry place away from heat, light and air (airtight jars work wonderfully)
