Since I started using boges I have only seen the ones like the ones on the left. I havent seen any with any color or coating. I have noticed that they have been more absorbent. Ive been getting mine from Vapor Alley,Vapor Beast and SureVapes they have been very consistant. Only thing is that they have been reading at 2.4 and a bit higher. This might be a reason that when using them with a ego or kgo (3.7
devices) that they seem to not wick well. Since I got my MOD kicked I set it at 8 watts and they have been working so much better. I even had to cut down on the amount of holes from 4 to only 2 very small punches. I dont get dry hits, and tons of vapor, the taste has been extra good since I got my MOD kicked.
