Kids love glitter. That’s a fact. And while it may be a pain to clean up - it’s even more painful for the environment. That’s why, if you are going to buy glitter, it has to be this one. The Mermaid Cave Biodegradable Glitter is made from a biodegradable film derived from sustainable and renewable raw materials. Unlike ordinary glitter which is usually PET- and therefore plastic-based, this is certified marine and waste water compostable.
