I have two 16 sided clear poison bottles. About 2 in. high With labels.. It reads... strychnia sulph. 1/8 ounce . Chas. Pfizer & Co. New York. One never opened (full ). Other one is opened (empty ) ..Can anyone tell me what they are worth.. I have been looking all over and can not find anything like them on the internet. I have many other bottles and have no clue what they are..
