Nice, but thought it included the glasses

Warning! All that you receive it a piece of slate. No glasses. No chalk or instructions on what this is or how to use it. I bought this as a gift for one of our clients and she had no idea who it was from or what it was for. There was no gift card enclosed (customer service said they sent an email to the client a week beforehand). I feel the picture is deceptive and caused me embarrassment with my client. Very disappointed with this item and with the customer service received on this purchase - not how Wayfair typically works.
