I’ve had no less that four Registration Label Holders go brittle as a result of sunlight exposure. On one occasion the holder fell off so I had to get a replacement label.
Yesterday I needed to replace the holder again and I came across a new Perspex holder made by a company called Stable Label Holder.
I purchased the label holder from FM Discount Spares in Shellharbour but I expect they will be available in lots of other motor accessory outlets.
The label holder cost me $9.95 and I was told it should last for 10 years.
