What buyers say about us
These are ratings of our store left by verified buyers on our eBay storefront — same company, same warehouse, same people packing the box. They are feedback on the purchase rather than reviews of this particular item. eBay’s one-click “delivered on time” feedback counts toward the rating but is not quoted here, because nobody wrote it.
★★★★★Verified eBay purchase
Seller was quick to ship the item, it was packed very well, which is good, because FedEx did not treat the box kindly, lol. The shoe’s survived in great shape and are exactly as described. Thanks! A++++ seller.
