90 acorns of 3 types [30 pieces x 3 types] Collected in the autumn of Reiwa 6 (2024). These were collected for use in preschool crafts and educational materials. They were very well-received at the site, so they are now available for sale! After boiling and sterilizing, each acorn has been polished with a cloth and sun-dried, so there is no worry about insects or mold. They are clean and safe to use. Also, once we confirm the completion of your purchase, we will polish each item with a cloth again before packing and shipping to check their condition. They can be used for crafts, making wreaths, as materials for making musical instruments by putting them in containers, etc... There are many uses! Why not give them a try? Returns, exchanges, and price reductions are not possible. Thank you for looking. (Please refrain from copying or imitating the text for sales purposes.)
