When blowing, the card should be presented. I don't know it very well either. In my opinion, it can be done.

In fact, I was in this line of work before, and I didn't do it for a long time, so I didn't dare to jump to the conclusion that you can't produce this. As far as I have seen, the glass feet in a semi-melted state are glued to the blown cup body and then pulled open and formed, so it is likely that this is difficult to achieve. Seeing your works, I feel a little emotional. If you are interested in these, you must go to the factory to have a look at the production process. In my opinion, if all your works can be produced, they will be in foreign markets.

Okay, okay, thank you
