Do you want to mark your collection? Do you want to be able to tell your samples apart easily? Do you want a quick overview of which sizes you have in your collection? Then use size markers.
Size markers, or size rings, click or slide onto metal hooks. This makes it very easy for you to organise and mark your collections. You can do this by using different colours or imprints on the size marker.
The advantage of size markers is that they enable you and others to see what you have in stock in an instant.
