    Awesome seller. Worked with me on a more detailed description & comparison of products and when received it was packaged very well. It’s a good quality tolex covering at a great price. I will say that delivery took a while but that wasn’t the seller’s fault. Carrier just sat on it for a while based on tracking, but it was worth the wait. Thanks! A+++++

    Nice item. One of the best Ebay seller. The seller did every thing to solve the problem as the original order got lost in the mail and sent a replacement order. Great communication in every way. Thank you so much for helping out.
