a mia nipote a cui l'ho regalato è piaciuto moltissimo ; ci siamo divertiti ad aprirli insieme e poi i geodi erano molto carini ; unica pecca che li avrei voluti più vari come finitura

Bought this for my friend’s son who is a young rock lovers. He loves it! Yet, it actually very hard to break and require support from adult to open it. Buy it if you know his / her parents won’t mind to help the little explorer. It’s a good experience. I think this box sets is in good portions. I know there is another box set that has more stones but charge just a little bit more. Very tempting, isn’t it? But after reading the reviews, the version with more stones brings higher expectations. So when the little explorer finds all the stones are actually similar, they become disappointed. And the helpers get disappointed as well (according to my friend, it requires quite some efforts to open each stone). So 4pcs version is a good experience. 10 pcs will be too much.
