Help, Where Can We Buy These?

On the boat we use towel holders like the ones shown in the picture. They're very convenient. You just jam a corner of the towel into the groove.

The trouble is that they don't last. All but one of our holders is broken.

Libby and I can't find a store to sell replacments. Do you know of one? If so, please tell us at dmills@acmenet.net

Thanks,
Dick and Libby
