I have a lot of oyster knives left over from when I ordered oysters, so I'm offering them at a low price (^^) [Set Contents] Oyster knives: 10 (8 blue, 2 black) [Product Condition] New: 4 Opened: 6 [Product Description] These knives are used for opening oysters. They came with the oysters. The opened ones were probably used once. One of them has a little rust, possibly because it was included with the oysters. Please check the photos. If you want to buy a large quantity, I can sell them for 300 yen each, so please comment (^^) #OysterKnife #Oyster #Knife #OysterKnife #Oyster #OysterKnife #Oyster
