Made with colored construction paper! Please use them as you like for making albums, message cards, etc. ♡ These are handmade items, so there may be some glue overflow or distortion. Thank you for your understanding. The acorns with hats that are perfectly attached are glued, but those worn by animals or slightly off-center are not glued. Please use them as you like. Acorns only can also be made. Please feel free to contact me. 1 square is 1 cm. Will be sent via Yu-packet Post Mini. 111
