This is my second purchase over the years from this shop and I can’t recommend them enough. I was looking for an assortment of mat colors for a gallery wall project and was so happy to see this shop excels in this regard in addition to consistent, excellent quality. Additionally, I accidentally ordered the wrong mat size and the seller was quick to cancel the initial order so I could re-place another one for the correct items. Thank you!
