Tearing difficult

I use the wipes for a erase wall calendar. Since small towels were just right, I always wipe only a date - so a small area. But this box is inappropriate. The cloths are led up through a small opening, from the outside looks a cloth tip. Pulling, tear, wipe cloth and the next tip should ready peep from the hole again. Tut's but mostly not. Pulling, tearing, next cloth tip away. The can is useful only if you completely lifts off the top and angling after the end of cloth in the box. This is impractical. Either the towels are too thin or the shear point is not perforated correctly or the can opening is not dimensioned correctly - I do not know what prevents the "Pull-tearing-cloth Next".
The cleaning effect is fine for small areas, for large under any circumstances. I often need two towels for an appointment entry (one line of 5-6 cm), because the first is immediately smeared completely and I had to take in the color inevitably soaked areas when other wipe.
