This is a set of 3D art displays with the theme of "LETTER FROM SPRING". The giant envelope is used as a carrier, surrounded by colorful flowers (such as carnations, roses, etc.) and butterflies, and the outline of the heart is outlined with rainbow lines. The colors are fresh and dreamy. Through the combination of flower art, insects, and romantic symbols, it conveys the beauty and tenderness of spring and creates an immersive spring atmosphere. It is suitable for shopping malls, cultural and creative spaces, etc., as a check-in point to attract people to feel the romance of spring and start a "letter dialogue" with spring.
