If you feel that your blind bags and boxes are monotonous, you can decorate them. You can prepare some ribbons, stickers, brushes, etc. Then cut out various patterns with scissors, and then stick the cut patterns on them with double-sided tape.
"Blind box" has become a new thing that little girls and boys like to try. In fact, it's not a new object, just a different way of playing. It is usually given to friends as a birthday present.
