I'm pretty sure it's just copper color, but the BE112 is the 801 atomizer sold by
BestEcig-Newest Mini E-cigarette|E-cigarette|wholesale e-liquid.
Clarification: The BE112 is a penstyle
compatible* with the DSE801, but it is manufactured by a different company (BestEcig) and has subtle (or not so subtle) differences in structure and performance. For example, these days, the 801 is high-bridge; the BE112 is low-bridge. Cart users say that the latter wicks better with carts. [I wouldn't know; I always drip.]
And it's not even 100% compatible. For example, the BE112 atty will not work the the XHALER, unless you use the adapter that NHaler sells.
And there are
other 801-compatible penstyles (manufactured by different companies): RN4072 and Joye302. My favorite to date is the Joye302 (low-bridge and two large air holes instead of four small ones): great TH and overall performance. The M201 penstyle also is great, but
not compatible with the others.
