Jellastic is a combination of Jellyfish and Plastic, which means the eco-friendly plastic we extract from jellyfish. This is a jellastic straw which made from jellyfish. If I say, "This product is made from jellyfish," you might be worried about whether it has a fishy oder. But if you actually smell it, you can figure out it doesn't smells anything. All of the materials used in our Jellastic are natural. No chemicals and No coating are used.
