I'm hoping when I finally receive the Poly Mailers I can give a better review, but still have not received them. I placed my order on September 19th . Received tracking information a few days later, but after several days of not showing tracking information, I emailed Polylush to inquire. Never got a reply so I sent a follow up email a few days later and they replied saying they were being shipped that day. I still have not received them, but... the tracking does show they have been shipped and should be here in a few more days. Hopefully they will be worth the wait.
