absolutely HORRIBLE. thin pages but worse than that, February has 31 days along with all the other months. I was hoping to give some as gifts and it would be bad enough to have 31 days in February once but for a perpetual calendar it is horrible. It isn't even made in China, it is made in Mexico and comes in cellophane.
This is a very useful product to keep track of birthdays. I purchased two - one to keep track church members, and one for family members! It has a spiral top and flips through the 12 months of the year. Plenty of room to write names on each line of the days of the year.
This is a perennial calendar great to remember all those family Birthdays, or other special dates and occasions. Especially good to help plan to send out traditional cards or media messages for loved ones' special days.
