How it's made. A half-balloon 120 or 180 mm tall, printed on its flat back with two walls and no infill, in matte or silk PLA for the latex look. The knot at the bottom has a 4 mm hole for a ribbon. The number and the name stand 1.5 mm proud in a second colour; the smiley's eyes and mouth are 1 mm recesses. On the back: a keyhole for a nail, a 20 x 60 mm recess for a Command strip, and a 10 x 3 mm magnet pocket. A bunch is three, tied with one ribbon.
