咕卡是由韓語的“폴꾸”而來，“咕”是韓文『裝飾』的發音，
咕卡也就是貼卡、裝飾卡片的意思。
韓國粉絲文化盛行，偶像明星的專輯中會附贈多張印著本人寫真美照的小卡片，
粉絲們為了能更好的收藏與欣賞，會用二片透明壓克力版保護小卡片，
並且在保護套做邊框美化的創意設計，
如今已成為2000年、2010年後青少女的文創娛樂。

Guka comes from the Korean word "폴꾸", and "gu" is the pronunciation of "decoration" in Korean.
Guka also means pasting or decorating cards.
Fan culture is very popular in Korea. The albums of idol stars will come with many small cards with beautiful photos of themselves printed on them.
In order to better collect and appreciate it, fans will use two transparent acrylic plates to protect the small card.
And the protective cover has a creative design to beautify the border.
Now it has become the cultural and creative entertainment for young girls after 2000 and 2010.
