I paid $24.95 for a single starter jar because I thought it being from Brod & Taylor & it costing $24.95, it would be a very high end jar. I purchased 2 jars and they were not the same weight. Through email, Brod & Taylor said I would have to purchase lab jars if I wanted jars to weigh the same. Had I known this, I would not have paid a premium for these jars & would have purchased Weck canning jars recommended by a professional sourdough baker. I would have saved a LOT of money, received the same results & received free shipping.
