I really like this Canterbury 18" x 24" Black Wall Mount Magnetic Chalkboard.  It comes with a small box of traditional chalk, eraser, drywall screws and a small level.  You can use traditional chalk or liquid chalk.  The traditional chalk writes very smooth.  You can hang it vertically or horizontally depending on how you want to use it.  The black wooden frame gives it a nice sleek look.  I chose to use it as a large calendar in my kitchen, it looks much better then the large paper calendars I had been using.  I love the fact that it is also magnetic.  The eraser works perfectly completely removing the chalk.  There is also a magnetic strip on the back of the eraser which keeps it securely on the chalkboard.  Can't wait to pick up some colorful liquid chalk to give my calendar more style and color.  I highly recommend this magnetic chalkboard, it is well made and works perfectly.
