Sorry to bump an old thread but I was what what others thought on this...
I just bought some RyJ Vintages in tubes. They are the glass tubes and have a cork sealing it. There is wrapper over the cork, so I suspect you'll damage the wrapper (not a huge deal) to unseal these. I've not come across tubos with cork as the seal. Usually it's the aluminum tubes with a screw top or glass (plastic) with a plastic top that pushes in.
The box I received came had 4 or the 12 with mold. I've spoken to the place I purchased these from and they are sending a new box. If there are some with mold on those, I can mix/mash so that I'll have a complete box without mold. The I can send the original back. This was the first time I've ever ordered something with mold on it. It's also been very hot these last few days here and I wonder if that effected these or it was the tubes.
In any case, should I open them even with a cork sealing? Typically with tubes, I leave the stick in the tube but open the top. Luckily, I've never had an issue going this way. These corks present a unique challenge. Here's a pic for reference.
Also, this was an interesting box. Came with a xikar crystal humidifier and meant to be a humidor.
