Thank you for the many positive reviews! They are also used as teaching materials in schools. Grown without pesticides. Each fruit is large and has strong, prickly thorns. ★While the standard size is impressive, we have collected only the larger ones of these cockleburs. After harvesting, they are dried and are now brown and sticky. (Some items may still be green. They will gradually turn brown.) You can enjoy playing with them, reminiscent of the old days. If your child takes them to nursery school, kindergarten, or school, they can become a star! Throw them at each other's clothes to see how many you can stick on, Make a target with a towel and compete, or play fishing games – there are many ways to play! Approximately 50 pieces (a little extra is included). If you have a desired number, please feel free to comment (^^) We also accept large orders. Simple packaging. We try to ship within one day whenever possible.
