Not bad for 50 cents each! The triangular (KV-1) round back is worth about $5. The rectangle (KR-9) is a little better bottle, $10-20 (although I saw one on eBay go for $51!!) They are both considered relatively common, but we all know that poisons in general are tough to find! Also, these are both American poisons. Way to go on finding a good deal! Jim
