After market lens hoods for Olympus??

The jjc is ok, but rather large (because it is reversible). It works just like the original, with the cover ring af the 45 taken away. It was too large for my liking, and I switched to this one:

Not reversible, but small, effective and permanently on my 45. I use a standard 46 mm lens cap on it. Had no trouble ordering it from ebay to the Netherlands
