Tamagotchi x MOS Burger 30th Anniversary Collab, Round 2, Is Here 🎉
MOS Food Services, Inc. (President: Eisuke Nakamura, headquartered in Shinagawa, Tokyo) has announced round two of its collaboration with Bandai’s long-running hit, Tamagotchi.
Tamagotchi first launched in 1996 and turns 30 this November — it’s basically a national icon at this point 🐣
This round features original artwork blending the world of Tamagotchi Paradise with MOS Burger’s menu items.
After last spring’s first collab proved so popular, it’s back for a summer round two!
It’s a treat for current Tamagotchi fans and anyone who grew up with the original, too ✨
All 4 Mos Wai Wai Set Freebies, Reviewed 🎁
This collab brings four freebies in total, each featuring exclusive, newly drawn artwork 👇
The Tamagotchi Sparkly Sticker Set (9 pieces) is a set of nine holographic stickers.
That shimmer factor is seriously irresistible 🌟
The Tamagotchi Mini Clear Case comes with a ball chain, so you can clip it right onto your bag or pouch — such a nice touch!
The Tamagotchi Letter Bag is sized for A5 paper, making it perfect for tucking away little notes or letters 📩
The Mametchi Ballpoint Pen features a rubber charm plate — easy to spot thanks to fan-favorite character Mametchi‘s design 🖊️
These freebies aren’t sold separately, so you’ll need to order one of the set menus to get your hands on them!
