I purchased this nativity/advent calendar for my 5 year old son. I was looking for something that was high enough quality to last through his childhood and with any luck, through HIS kids childhood. This unit is built out of pressboard, and is good quality. With care it should last generations. The magnetic background allows your children to create manger scenes with ease and it is fun for the whole family. The only drawback to this unit is the lack of any type of base or stand. Due to this fact, I recommend that you mount it on the wall if possible, so that your kids don't pull it over when trying to open the little doors (which are kept closed by magnets). Over all I am very pleased with this Advent Calendar, and I do recommend it!
