I've had this set for so long now, I think even before I turned one. My grandma bought me this set after she saw me getting it at NBS every time we were there. But I think they got this particular set at Market! Market! during a toy fair.
The wooden case is not very useful after opening it as it is only covered by plastic which you can't put back on. However, you can use it to display the collection or for pattern play.
I wish there were more Melissa and Doug products here. Toys 'R Us seems to be running out of new stocks. This particular one is no longer available but I think you can still get it at NBS.
