I think that the piece of sponge in the mouthpiece, is an attempt to absorb consendsation. I dont know if it is good or bad .... I will wait to hear from you that got them. I feel that they may get "stale" after time after absorbing and being saturated (not to say we cant clean them.. Lets hear after a week or two!
oh ok, I get it. the carts from breezesmokes did not come with blue foam in them. keeping in mind that although I have been vaping since feb, I still use my joye 510 the most and of course carts (I also have a riva 510) so I am not all that experienced, but I remember thinking when I first started using these clear carts that I thought they seemed to vape better after they got a little condensation in them. is that weird? or maybe at that stage the polyfill was damper.....? who knows, I can be a little weird
