This is Bauway’s standard 510 cartomizer. Bauway is big in Europe, but has yet to gain a foothold in the American market.
Bauway, at this time, is fairly popular in European countries, but still not a dominant player in the US market. The only reason for mentioning that is to shed some understanding on why you may not be familiar with the manufacturer. The 510 cartomizer is similar in look and functionality to cartomizers from other manufacturers. It uses a fixed inner coil and poly-fill stuffing to hold the e-Liquid.
