Uber Rare JM Johnson Matthey 10oz as its Blue Oyster bar 1/1 known #000004 in factory seal which is dried out cracked on corners and edges but it’s the original 100% guaranteed. The marks you see in the pics are the plastic for full disclosure This is a truly most likely the only time you will have the chance to own this 10oz variety. You decide if it’s for you.

Thanks for looking and sharing our passion for this hobby.

Cheers
