    • Small jars
    So far so good other then one of the jars had contamination I let them know just waiting on a reply but I love the customer service and the quality product I just wish they had a 32oz option for BRF the small jars are a little annoying when your intentions are to go bulk substrate but for shipping packaging 10/10 for quality 10/10
