Toothpaste designed as a two-in-one - Micro Wonder Life

As far as I can remember, it seems that the packaging of toothpaste has not changed except for the material. Apparently people have got used to this design, but it does not mean that there is no room for improvement.

Korean designers Sang Min Yu and Wong Sang Lee were inspired by milk cartons and integrated the paper packaging with the tube itself. You just need to break open both ends and pull the self-sealing strip to use it. It is said that squeezing toothpaste in this way is less effort, and you can use every bit of it. Most importantly, it saves material costs and transportation costs. What do you think of this design?
