The sheets of Bierbaum (which have often already previously purchased here) is processed really great. The metal zipper summarizes super. The Mako Satin is really fine and after the first time everything perfect washing. Unlike eg Kaeppel the material is not "Pollig", so do not get this weird textile lint through washing or by scraping (Bart) ... Honestly I will never buy again something else, because I with Bierbaum am become really lucky and happy!
