MV Glass Core (GC): you will get a strong and dense vapor, increases passive/conduction heating that improves extraction and decarboxilation. A water tool is recommended.
MV Teflon Core (TC): for a soft and subtle feeling, keeps the terpens (taste and aroma) for a long time. Optionally, the decarboxilation kit can be installed for heating effects (convection-conduction) that are similar to the use of a glass core.
