The team members of iO felicity company limited come from Tainan, and all product manufacturing, design, and development are rooted in Taiwan. The name of iO felicity company limited is derived from the homophone of the Italian word "iO", which means "I" or "mine". iO felicity company limited hopes that our products can be truly loved and used by users, making them feel from the bottom of their hearts, "This is mine!" Only in this way will they use them frequently and cherish them, achieving our original intention of reducing waste.

The design philosophy of iO felicity company limited is to ensure that resources can be sustainably recycled and regenerated right from the beginning of product design. Therefore, we start with product redesign, embedding practicality, circular supply, resource recovery, product lifespan, and service into product design (Form follows function), thereby conveying the concept of transitioning from a one-way linear economy to a sustainable circular economy.

In the beginning, we were just a small team that loved Taiwan's beverage culture, hoping to start by using eco-friendly cups to reduce the use of disposable beverage cups. We used many eco-friendly cups one after another, only to find that not a single eco-friendly cup was universally compatible with all drinks. One that could be used to buy hand-shaken drinks could not fit under a coffee machine to buy coffee, while one that could buy coffee could not hold a 750 cc hand-shaken drink. Because of this, we had to prepare a shorter cup to buy coffee and another large-capacity cup to buy hand-shaken drinks... Gradually, we accumulated more and more cups. When carrying a large eco-friendly cup, buying coffee was not feasible; when carrying a coffee cup, wanting to use it for a hand-shaken drink on a whim caused inconvenience to the store clerk. As a result, we repeatedly went back to using disposable cups... We thought that if there were an eco-friendly cup suitable for all beverage scenarios—one that was also good-looking, lightweight, and convenient—it would gradually increase people's willingness to use it and slowly reduce their chances of using disposable cups, which would surely make users truly forget the convenience of disposable cups. Finally, in 2018, the hand-drawn sketch of the Turn Turn Cup by the designer of iO felicity company limited was born. In the same year, we applied for the first version of patent M583247 for a detachable cup. During the continuous optimization of the design, the designer of iO felicity company limited, in order to enhance the storage advantage of the cup body after disassembly, added threads to the outer edge of the bottom cup. Since then, the disassembled cup body of the Turn Turn Cup has a place to go. We also applied for patent M593787 with this design, and the Turn Turn Cup was born...
