This is a Focus Cover for the Canon Speedlite 430EX II.
You can use this cover to concentrate your flash on one specific object.
This is a good replacement for the often used 'Pringles can with straws'
NOTE: Since the Black Strong & Flexible has a somewhat grainy texture this COULD leave some small traces on your flash because of the tight fit. Nothing real serieus, but worth noticing.
