智海〈紙換紙〉，描繪一本書的生產和買賣過程：紙鈔換紙張，印刷裝釘成書，賣書換紙鈔。物料和意義的累積，價值的交換，循環不息。
 
這作品製作成封箱膠帶，適合包裝郵寄、出貨或送禮，喻意貨如輪轉，禮尚往來。
 
This is what we do as a publisher: Banknotes in exchange for papers, papers turning into books, and the books in exchange for banknotes - all are papers in essence. 
 
Chihoi’s Paper for Paper is all about the accumulation of materials and meanings, and the endless exchange of values. We produce as packing tape that rotates endlessly; perfect for packing, mailing, sending goods and gifts. We sincerely wish you good business.
