My previous experiences were amazing but this last order took 4 weeks to arrive. This was caused by a combination of the item being on back order and then being lost by usps. There was no tracking information from the post office and very little communication from seller. I don’t blame him for the post offices mistakes but I didn’t know about the item being on back order until I called 10 days after purchase. When the items finally arrived they were excellent quality as always so I would buy from him again in the future but I would hope to be notified if an item is not available to ship at the time my order is placed.

I recently ordered from this company, and I was blown away by how smooth and fast the entire process was! From the moment I placed my order, everything moved quickly and efficiently. The delivery arrived right on time, and the packaging was top-notch—truly some of the best I’ve seen in the industry. Everything was secure, neat, and gave a premium feel when I opened the box.
