This art work began while I was unpacking delivered presents. I noticed that all things either fragile or valuable were all wrapped by air vinyl. This inspired me to create this artwork with a pen. In this work, one cannot see what is inside; still, one knows that what is inside the vinyl must be precious as it is protected by air vinyl. Through this art work, I could explore pen-drawing techniques as well as think over what is valuable and precious, which is hidden from our eyes.
