生活痕跡千百種，如:握筆、開關燈、流汗印、齒痕、壓痕等，人人會有所區別，同一個人在不同狀態下留下的 痕跡也不盡相同。將這些痕跡具體表現並長久的記錄下來，會產生有趣的不規律性，能讓人看見自己平常生活的 細節，也看見與他人的差異，使人們能用不同的眼光觀察生活，增加生活樂趣，創造另類話題。
People have made thousands of traces in lives, such as, a dent on a pen, sweat stain, and bite marks. Each person leaves their unique traces, and one may leave different traces under different conditions. By collecting these traces, we see interesting irregularities. These allow people to notice the details of their daily lives and the differences among each other, so that people can observe their lives in different perspectives and have more fun to their everyday life while creating appealing conversations.
In order to display life traces concretely, people from various backgrounds are invited to join our experiment. We asked them to hold and press different objects to record their traces with soft materials and paints. Also, we took photo of what they have left traces on.
食器是我們吃飯的用具，是最平凡接觸的物品之一。起先我們想將一般的物體留下使用痕跡後創造品牌產物，於 是進行了幾類實驗。這些實驗的結果促使我們將其轉化成為規格化產品。於是我們歸納出幾種端拿的痕跡形式， 並將這些手勢結合碗、盤、杯，再經過修飾轉化，將痕跡變成造型美感，也增加使用樂趣。
Tableware is the most common and important object we get in touch with every day. At first, we wanted to create our products by leaving traces on regular things, so we conducted several types of experiments and investigations. The results of these experiments prompted us to turn them into standardized products. Therefore, we summed up the traces that are commonly done to take tableware, and combined these gestures with bowls, plates, cups, and then modified and transformed the traces into beautiful shapes, which increase the fun while using them.
用手印出的圖形是我們品牌形象的視覺元素;食器、飾品等帶有裝飾、紀念意義的物品是我們轉換結合壓痕、使 用習性而生的產品。與品牌名稱相呼應，我們認為有使用的東西才是「有用」，預設的手感痕跡也是一種美感。 『印恆』，一個真實、實驗性、且正在發生的品牌。
Handprint pattern is our visual brand identity. Decorative, memorable tableware and jewelries are the products that we create by transforming pressing marks and using habits. Corresponding to the brand name, we think that things can only be called “useful” when they are actually use. The default traces left by hand also have a sense of beauty.
"Ing hand" is real, experimental, and ongoing .
