This was a very bad experience, with the supplier making a bulk production that was completely different to the approved sample.
They originally produced and sent me a sample which was exactly what I wanted, so I approved the bulk production. I asked the supplier multiple times to send me a photo of the production version prior to sending, which he ignored. When the bulk product was delivered, the products were made in a completely different material than the sample that I approved, and the logo was printed in a different size and position. The version that produced did not match my brand at all, and the difference in size & material meant that it could not fit into my packaging. I have since had to throw it all away, a huge waste of money, time and material
Worst of all, the supplier refused to acknowledge that the production version was any different to the approved sample, continually telling me that it was exactly the same. It is very obviously different - see attached photos.
