Not very reliable delivery service
Review by confirmed purchaser
I requested the service and the envelope took over a week to arrive and had no padding included or postage. I was sending 2phones and there wasn't room for both so requested second envelope but never received it so sold elsewhere. Emails came chasing me about late delivery of the phones but that was because the envelopes were received late then not at all. The payment for the one phone I did sell was complete within a couple of days after they had received the phone.
