Muji’s suitcase has the build quality and practicality to compete against brands like Away that are getting very popular due to their simple designs and “smart” capabilities. The lack of the battery pack in the Muji suitcase is actually a good thing because TSA is cracking down on luggages with batteries. If you buy a Muji suitcase, you don’t have to worry about this AT ALL.
At the time of this writing, you can get the suitcase at a discount as well! Check it out here: http://www.muji.us/store/special-theme/muji-to-go/suitcase.html
