Question about ISI Capsules

I bought the capsules for the original iSi Gourmet Whip. I find the name Kisag misleading here. Kisag capsules are available in Migros and they do not fit the iSi Whip.

The Kisag iSi capsules mentioned only fit an original iSi blower. This is not available in Switzerland. I bought my cream blower from Amazon.
