Sold UNPAINTED (presentation suggestion therefore painted on the photo) They clip in the same way as standard LEGO CITY rims
!!!!!!!! Warning for children under 18, you must do this accompanied by an adult!
Advice for painting: A standard spray can is enough, DIY store, read the instructions on the spray can carefully to avoid mistakes. Don't panic if you fail, take "acetone" to remove the paint, mix with the rim in a container for a few seconds will be enough (be careful gloves and mask recommended).
