I've always ordered the menthol samplers and last week decided to take the plunge on some Kamel Menthols.
I got a few boxes and they all had a funny aftertaste, not sure how to describe it, but it was deff not right. Stale or musty, just blah.
I thought I had ordered the wrong type and sent in an email to customer service to figure it out for future reference. I also had some of the menthol samplers come in with my order (that included the Kamels) and they tasted great .. Mmmm.
I noticed that you can smell the weirdness without even
vaping them, it's that noticeable.
Anyway, customer service thought it might have been a bad batch and were happy to help me out. Give them a shout and see if that helps!
