Transit time depends on the carrier selected. USPS and FedEx Ground/Home takes approximately 4-8 business days (depending on location). FedEx Smartpost is generally the slower method as FedEx transports to your local Post Office and the Post Office makes the final delivery.
Orders ship within 1-3 business days from the date the order is placed. Transit time is determined by the carrier you have selected. FedEx SmartPost is cheaper but slower than Ground and USPS as FedEx transports to your local Post Office and then the Post Office makes the final delivery.

The number in the parenthesis provide the neck and thread count. You want to make sure the neck size (first number) matches. Some threads are interchangeable like 400 and 410 so a 20/400 bottle would fit a 20/400 and 20/410 closure.
The second number in parenthesis would be the thread count. The first number is the neck count. You want to match these when finding bottles and closures. Note: Our 400 and 410 threads are interchangeable.
