This is like a kinder egg. For the price of one mouthpiece, you actually get an additional blend chamber just in case you want to give your old blends another go.
The Mouthpiece Chamber was designed and manufactured with the Iolite Portable Vaporizer in mind. Not only does this package include a replacement mouthpiece and blend chamber, but it also comes with one Blend Chamber and one Short Mouthpiece.
These accessories are very easy to attach and maintain so your vaporizing experience should be hassle free.
