Attention, these laminating sheets are for an A3 laminator!
I speak from experience as they may say they are A4, but what actually happens is that the binding of the sheets is on the long side, intended to be used in an A3 laminator in landscape orientation and not in portrait.
I am forced to use them in my A4 laminator since I bought them, opened them, and they are not cheap (until they run out).
As a result, sometimes there are a few wrinkles during lamination and overall it is not as strong.
Even though I shouldn't give stars since I am not using them as intended, it seems to me that they are of good quality but I don't know if they are worth their price compared to others that do a similar job at half the cost.
