Davidson® Dye Expiration

The Davidson Marking System® Tissue Marking Dyes have an indefinite shelf life. This is why we do not post an expiration date on the bottles. However, there is an evaporation factor that requires attention to cap tightness and shelf rotation.

We recommend checking cap tightness when stocking and to rotate stock off your shelf within one year of receiving the product, using the oldest bottles first.
