About Flutes cartridges:
Flutes cartridges hold up to .35 grams of dry-herbs and can be smoked in two sessions by switching from the first bowl to the second with a twist.
Store freshly packed cartridges in the red silicon sleeve to bring with you as backups on-the-go. No need to bring a grinder or bulky equipment with you on adventures. Just quick-change and you're ready to smoke again.
After they're finished, slip the cartridge back into the silicon sleeve to seal the smell inside and store securely in your pocket.
