I could be completely wrong, but I just got a new case of the Bellissimos and the tapes look wider than the last case I had. They also seem to be smoother when initially unfolding them and sticking them. If they did change them, then it was definitely for the better, since I'm having no problems with them at all.
If anyone has an older Bambino to compare, I have measured these tapes to each be 1.7 inches wide. Has anyone else recently gotten some and noticed anything different?
