Perfect cork and whiteboard combo
January 1, 2023
I looked all over the web for a large magnetic whiteboard that not only was high quality, but could also be delivered without hassle and damage—something I found rampant in reviews on other sites.

I chose MyWhiteBoards after having a conversation with one of their sales associates (I want to say his name was Chris, but it may have been Micah—as I said, I did a lot of searching in the web). He answered my questions and I felt confident I picked the right product. (The map rail really is a great feature).

Long story short, the board was extremely well packaged, relatively easy to hang (two people!), and it will be a huge asset to my small business in the coming year.
