Wrench/Spanner for removing the special retainer of the car radio antenna mast

This was made to remove the special retainer of my Toyota Camry radio antenna mast. The special retainer has to be removed with special factory tools.

With this tool, the job is easily done.

There are many retainers in different shape on the market. This one fits my Japan version 2004 Toyota Camry. I hope it will fit yours too.
