○△□ is a tart specialty shop specializing in ’souvenirs’ and ’takeout,’ with the concept of being able to ’pop it in your mouth with one hand!’ Its charm lies in the convenience of eating it like a snack while enjoying the visual splendor of the tarts.

With bright strawberry as the main focus, mixed with a layered sauce of raspberry and blueberry, the sweet and sour elegance and blissful deliciousness spread through your mouth with just one bite!

If you love cheese and berries, you definitely have to try this! That was the delicious Custard Cake Berry Cheese Tart Flavor with its fluffy texture!
