Description is incomplete. Thanks to a small Fummel Fritzen we have found that even the Swimming Ring can be decomposed into two parts (red and white with males). Then the filling and emptying is not a problem anymore. As well seems to have found no admission into the enclosed list an operation step. Pity! If we had not found out, we'd swear even this tea infuser. The build quality is superb - quality that is worth the money.
