Loved my experience with OKWISHING. Everything is low cost or very reasonably priced. My items shipped quickly and arrived sooner than expected. The quality was great and each item looked exactly as pictured. I did make a few returns but only due to sizing, and I ended up replacing most of those items with the correct size because I liked them so much. The return process was super easy and I received my refund in a timely manner. I would definitely recommend ordering with OKWISHING! I will for sure be a returning customer.
