This item has been treated to prevent bamboo deterioration. Wood ash was boiled to remove the astringency, and then applied to the bamboo in three coats, dried in the sun, and finally coated with camellia oil. There are no noticeable scratches, and it should be perfectly usable. A feeder can be added for an additional 400 yen. Instant purchase is welcome. *Please note that the stepping net in the second photo is not included.
