Have placed many orders in the past months with sales representative Brittany Cornish and couldn't be more pleased ! She is always a joy to speak with, and she always makes sure that my orders are delivered on time. She's a great asset to your team but I'm sure you already know that.

Received order very quick. I was totally impressed with how well it was prepared for shipment. While a fragile order, it arrived undamaged in any way because of the excellent packaging. Thanks.
