Erst einmal das Gute: Die Nuss passt spitze und sitzt auch stabil an schwierigen Stellen. Das macht Sie mit einer kleinen Kugel. Leider verpackt der Lieferant die Nuss in der Einzelverpackung so schlecht und kompliziert dass ich mir erst einmal den Fingernagel beim Auspacken abgebrochen habe. Mit einer Zange ging es dann. Die Nuss hat 5 Sterne verdient die Verpackung 1 denn die Nuss kam ja heil an. Ich gebe deshalb nur 3 Sterne weil Leute die mit Werkzeug arbeiten eigentlich auch die Nutzung im Auge haben sollten.;
