Stanzen fürs Sicherheitsgefühlt 😄Man hat sehr viel spaß wie beschrieben beim Stanzen 😅Ich bin komplett zufrieden finde es eine sehr gut gelöste Methode im vergleich sich die Namen auf ein Zettel zu schreiben. Nur das mit dem Online Blog habe ich nicht ganz zu gut verstanden. Da hätte ich mir eine schönere Seite gewünscht jedoch nach bisschen googel auch zu finden. Falls man es braucht.
Ich persönlich würde es weiter empfehlen 9/10 👍🏼
