where can I find the plastic closer dividers for your labes OL2486WX Thank you

We don't have a specific store to recommend. However, you can do an internet search for "closet rod dividers" or "clothing rack dividers" to pull up several options. Most of the standard clothing rack dividers should work well with the OL2486WX.

Will the print on the clear frosted matte labels show up on a richly colored closet divider rounder (hot pink and kelly green)?

The Clear Matte Inkjet (CJ) is transparent, and since home and office printers cannot add an opaque layer to the printed area, your design will have a certain level of transparency. The color vibrancy would be more apparent on a white material in comparison. With this in mind, we suggest darkening designs and applying the labels to light or clear surfaces for better contrast and readability.
