Multifunction Vape Pen and Electric Dab Straw EVRI by Dip Devices is a multi-functional consumption solution.  The EVRI vape features a powerful 900 mAh battery that connects magnetically to continuously evolving attachments. These include the Vapor Tip Attachment, which allows consumption of concentrate directly from its container and the 510/Flower Attachment, which has one side that connects to 510 cartridges and one that allows you to consume flower. The EVRI dab straw and pen evolves with consumption, so many more attachments are coming soon! (Note that the 510 cartridge and flower attachment are two sides of the same attachment--cartridge pictured not included with attachment.) For optimal performance and flavor, replace vape attachments every 6-8 weeks. 1% of all EVRI sales donated to drug policy reform via MPP.org and SSDP.org.  An additional 1% by color is donated as well:Black: Racial JusticeRed: Blood Donation ActivismBlue: Marine ConservationGreen: Reforestation and Land ConservationCosmic: Breast Cancer Support Delivery of this device will require an adult signature and cannot be shipped to a PO box.
