Amazing tool for Amazon FBA labels. It is very fast and saves so much time from using its extension. Now works well on both Chrome and Firefox. It resizes labels from its web site on resizer menu. It has great features like SeparatorLabel between each series of FNSKU and Item Number on each product barcode label. Seperator labels make it easy to see where each product barcode starts and ends. Item numbers keep track of how many you put in a box.
