Little Twin Stars and My Melody are celebrating their 40th Birthday this year. The cute Sanrio characters surprised customers in Hong Kong‘s shopping district Causeway Bay with a pop op store and an amazing exhibition, including a dream house, a flower truck, birthday cakes and much more. We found lovely pictures on the Hong Kong website jetsoclub, showing that the cute bunny and Kiki and Lala have become just as popular as their big sister Hello Kitty. The store in the colorful little house offers some special limited edition products, like kawaii pink anniversary backpacks. Fans can visit the exhibition until the end of August, but we just can’t wait to wish a Happy Birthday.
