Limited-Time Pop-Up Shop for Good Glass at Ueno Marui
Mark your calendars! From Monday, December 22, 2025, to Thursday, January 8, 2026, a special pop-up shop for the brand Good Glass will be open at the event space on the first floor of Ueno Marui. This exclusive event is your chance to get a look at the social media sensation—the “giant Hello Kitty” ornament—along with the highly sought-after Hello Kitty straw and glass set that’s been out of stock for ages.
What is Good Glass?
Good Glass is a charming brand that crafts double-layered glass products featuring adorable animal and character motifs. Their star items are the double-layered glasses, but they also offer eco-friendly glass straws. The magic of the double-layered glasses is in their design: when you pour a drink, the inner motif shines through clearly, adding a visual treat to your sips. It’s this blend of beauty and practicality that has made them a favorite for everyday use and as gifts.
Here’s something extra special: every single piece is handmade by skilled glass artisans. This means no two items are identical, giving each one its own unique character and charm. True to their name, Good Glass lives by the concept of “making every day a little better (or ‘good’)” by creating glassware that’s a delight to see, use, and even display as decor.
Hot Products at the Pop-Up
The pop-up shop is packed with must-have items! Look out for the new 70th Anniversary Miffy Straw, the once-sold-out Hello Kitty glass and straw set, and the show-stopping Premium Giant Hello Kitty Ornament—this massive piece is about 10 times the size of the regular version and caused a huge stir online when it was revealed.
But that’s not all. Alongside these character-themed goodies, you’ll also find original glass designs with animal motifs, offering a wide range to choose from. Plus, don’t miss the specially designed glass straw commemorating Miffy’s 70th anniversary, which started sales on December 5 and will be available at this pop-up.
This anniversary straw is a real looker. The straw itself and its silicone case are decorated with a 70th-anniversary logo and delicate floral patterns, giving it a sweet and elegant vibe perfect for the celebration. And in a cute nod to fans, the silicone case comes in Miffy’s signature orange hue.
It’s not just a practical item for daily use; this limited-edition straw is also a fantastic collectible or gift. Remember, all these wonderful products will only be available at the Ueno Marui pop-up shop during its run from Monday, December 22, 2025, to Thursday, January 8, 2026.
