Question about sticky bricks

[terpojones35]

Does the glass mouthpiece from the sticky brick runt work with the junior?

Yes but it will prevent the lid fitting on the body of the junior.

Yes but it will prevent the lid fitting on the unit of the junior.

That’s all fine with me
I was asking because I wanted to see if it was possible to have it both as a comfortable home unit while also being able to use the short mouthpiece with the lid for portability.
