Really small parts that might easily break off, but are not on the carillon. The wooden frame is very verweindungssteif. The metal parts have a good surface finish, in any case you can not scrape off the paint with his fingernails. If you want to improve something in this regard: You could easily round off the plates.
The sound is extremely good for a "toy" in my opinion. The clapper can be stowed in the holes and then do not go so quickly lost.
The enclosed book you do not need (of notes) knowledge, provided reading.
The bottom line is the carillon is highly recommended.
