The square shape makes bulk packaging much easier, because the jars fit flush along the sides of whatever box they’re being transported in. It also provides more surface area than a round jar, making labeling and custom branding a breeze. The lid complements any brand colors and provides a child proof closure that is compliant with all state guidelines. Push the cap down and twist to unlock. The 9ml clear glass jar can hold 1 to 2g of concentrate. Made of thick, durable borosilicate glass, the clear glass allows you to see exactly what is packed inside. This allows the customer to get a glimpse at the precious nectar without even needing to open the container. The thick glass is highly resistant to shattering, and the jar can be reused countless times by the customer. These flat, compact concentrate storage jars are available in a 250ct bulk box.
