    The sample loops I purchased from this seller arrived quickly. The items were in excellent, brand-new condition as described by the listings. The seller took extra care to ensure that the items were well-packaged and protected during shipping. I also hugely appreciate how quickly the seller responded to my request to have both items shipped together to reduce shipping fees. Overall, I strongly recommend this seller!

    AAA+++ seller! Highly recommended! With this item, the seller delivered a Master Class on how to properly package an item. It was satisfying undoing multiple layers of bubble wrap, each wrapped in plastic film and taped, to obtain the item I purchased, and finding no shipping damage! Accurate item description. Fast shipment. Thank you!
