Why settle for anything less?

The Master Kase Nintendo Switch Sling Bag is an always-on-the-ready eco-friendly bag must-have for hardcore gamers, offering unmatched protection, organized storage, and a built-in gaming stand for your Nintendo Switch and OLED. It's a must-have for gamers who can't bear to be separated from their beloved console.We tried our best to launch it as pretty much the same time as "The Legend of Zelda Tears of the Kingdom". So all Zelda gamers (including ourselves) could play it anywhere, anytime.

 It is named the Master Kase, since it’s for Game Masters who care how they carry and play games.


 Let’s go through some key features.The Master Kase is a light, safe, and always-on-the-ready eco-friendly bag, that lets you game anywhere with ease.

High-Density Foam Absorber

What's your Carry Style?






For many companies, it is not smart to design a sling bag for Nintendo Switch Console during its 7th year after it released back in 2017. Yet, we believe as long as this bag comes at the right time, supporting some gamers (like ourselves) enjoy the joy of gaming and exploring, just like what we enjoyed the first Super Mario or Final Fantasy 7 before, it worthies. Right now, this sling bag is under production now and should be ready to be delivered in mid July. Stay tuned, we will update the product detail page soon.
