I came across a deal on ball lock kegs but had to overbuy to get the best price. I have four extra ball lock kegs with relief valve lids.
These kegs are retired Pepsi kegs that were purchased by NYSoda and used to hold their soda syrup. They are recent empties that I bought from the distributor. They are black top two handled kegs. They have some stickers and superficial dents but hold pressure fine.
$40 each or $150 for all four. I will ship at actual cost.
