Shure olives to Hippo VB; are these what I'm looking for?

[megabyte]

Hi,
I'm hunting for sleeves for my Hippos. I hear a lot great about the Shure olives, i.e. PA910 / EABKF1, but all the threads are old and outdated.
Are these sleeves legit, and from a good reseller? http://www.ebay.com/itm/10-MEDIUM-Fo...item2ea6cc0e50

Or does someone know a better way of buying these when living in Sweden?

Or is there an even better alternative than the olives that I have overlooked?

Thanks!
