QSL de Z21BB

More and more stations are QSLing via eQSL. And lately there are a lot that have a nice designed card. Like the QSL from Z21BB, Zimbabwe. If you like paper QSL, the eQSL site is for you as if needed you just print them out. A real advantage over LOTW.
Z21BB has W3HNK as QSL manager, I've been looking for his QSL policy but cannot find it, so I guess it's ok via QSL buro. The website of W3HNK can be found here.
