As long as you sell this product I will continue to buy it. So many times I've brought packs of paper to find that half of it is missing lines. I have never had this problem when buying these packages.
I prefer the sheets to be bound in tablet form rather than loose. However I do not like the lined cloth bound (at the top) tablets you sell with perforated sheets that have the top at the top edge on one side and at the bottom on the back side (i.e. you turn them upside down to use the back side). I prefer lined paper tablets with a gum binding at the top that can be removed easily without tearing. The sheets should be lined so that they are the same on both sides when you turn them over from right to left (as in a book and like the loose sheets I purchased). I prefer the sheets not to have holes as sometimes I don't want holes and when I do I can punch them myself.
