I bought this in Taiwan. The bok choy part seems to be made of glass. This "bok choy strap" is a popular souvenir from Taiwan. In Taiwan, bok choy is considered an auspicious symbol, representing "prosperity of descendants," "living to 100 years old (longevity)," and "bringing good luck." [Easy-to-Use Strap] The red strap can be easily attached to smartphones or bags, making it convenient to carry around. I placed a paper clip to show the size. - Color: Green and White - Strap Color: Red - Design: Vegetable motif (bok choy) Thank you for looking.
