Illuminated Musical Card: Unlike ordinary greeting cards, our cards deliver heartfelt blessings and unexpected surprises to your loved ones, family, and friends. Exquisite Design: When you open the greeting card to 90 degrees, the exquisitely and vividly cut 3D paper pattern will slowly unfold before your eyes. When you want to put the card away, just close it, and it becomes a flat card that doesn't take up space. Superior Material: The greeting card is made of special paper with a certain hardness. In addition to the 3D pattern, there are some small fine details added inside the greeting card. You can express your love, blessing, or gratitude to the gift recipient with a few words on the included envelope or in the blank space inside. Special Gifts: If you're not good at expressing yourself on special days, our musical birthday cards are the perfect gifts for birthday wishes. This meaningful card helps create a festive atmosphere. It's suitable for birthday parties of all ages: women, men, girls, and boys. Note: Do not squeeze the card or allow it to get wet, so as not to affect the card's lifespan.
