Had the toothbrush canceled because the delivery time was too long, and my visit to the toothbrush quickly needed. The Ersatzzahnbürsten I hette dazubestellt and thus canceled these Bestellubg. After three weeks, put their things, suddenly in the mailbox. I thought, I can take for my toothbrush, but they did not fit! Now, return the opened package? Surely it is not because of the article? but stood for all common toothbrushes and that's not true!
