    Worth it!
    I bought these as a fun project to do with my kids and they did not disappoint! Four of the five rocks were beautiful geodes, one was just a nodule. The nodule was extremly hard to crack... Nothing my husband, a metal punch, and a handheld sledge couldn't handle! We will polish the inside for a nicer look. The other rocks were realitively easy to open... My seven year old was even able to crack one! They recommend the sock method, but if you want nice clean breaks I would not go that route. All in all, I am very satisfied with the product we received and will buy again!

    Got this for my 10 yr old boy. As other reviews suggests to wash, I did so. I let them sit in water over night, they were quite dirty. One came in already cracked a little disappointed ab that. Aside from that, it was a lot of fun to crack and they are beautiful inside.
