Voltaren logo

These letters are from the same company as Voltaren (don't know what that is either) but on a different product.

Any help identifying this would be appreciated



Don't know this one or at least the one that has been customized.
Some fonts you may consider for a customization: Aller, Ubuntu, Veto, Dax/Daxline, Karbon, Typecache | Font Clusters: Sans Serif Fonts with Lowercase Spurless ‘a’
