- r***d (695)- Feedback left by buyer.Past yearVerified purchaseAwesome 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+++++Tolex, Light Weight Black Bronco, 54" Wide, Cut to 1 Yard (#126614772956)
