Do you guys know the Rail Box ? The rail system is absolutely unique…Some kind of billet box but as far as I know it works with every RDA/RTA on the market and it embarks a DNA 40 ! It’s made in France by Vape Tools. There is already a waiting list on their website : vape.tools/en/ Their FB is updated regularly www.facebook.com/vapetoools Quite interesting isn't it ? Did somebody try this box, or found a review ?
