Based on my experience with this product, it`s a great solution for managing grommets. The organizer is made from durable plastic and holds up well to use in an industrial setting. The different tray sizes allow for organization by size and the clear lid makes it easy to see what's inside. The only con is that it can be A bit difficult to remove grommets from smaller trays. Overall, a great addition to any industrial and scientific workplace in need of grommet management. .
