Boro
The Boro platform, originally developed by Billet Box Vapor as the Billet Box R4 Boro, is the largest ecosystem of support of all fully integrated all-in-one (AIO) systems.
Within the "Boro" umbrella, falls a multitude of third party devices, accessories, integrated mouth pieces, coil bridges, RBA's (rebuildable base atomizers) and more - all built around the Rev4 (R4) Boro Tank by Billet Box.
