I have been culling my inventory and have the following cases available - size 12 - 12 units, size 16 - 5 units & size 18 - 21 units. These slightly warped [inward] tops and/or reluctant dome fasteners. Nothing a stout rubber band will not fix. Selling at less than cost - minimum 5 units - mix and match - $50 plus actual postage. I will periodically adjust the numbers. Please email fermenthaus@gmail.com to get prompt attemntion
