For the 5 years I have been vaping,I have used only cartos. I am finding it hard to find the Boge slotted cartos. I buy from Sure vapes,but they are always out,I was told they would be back in stock. Desperate I went to my BM and bought an Aspire Nautlis. My question is,what is comparable to a carto? I do not care for this nautlis. Does anyone know where I can get Boge slotted Cartos? I even looked at Iken vape and they are out of theirs. I guess cartos must be a thing of the past,but I like them and change is hard.
