This is an old insect collecting tool. It seems that chemicals were put inside and used. It's in its original condition, and the outside of the bottle has been cleaned. The items for sale are only those in the first photo (books not included), but there are several. You might get a good look if you put a dead cicada or insect in it. If you don't like insects, and if you wish, I will clean the inside before shipping. Thank you.
