We authenticate keychains and other
Coach items in this thread too. We need the same information that's set out in post number One - item listing, auction listing URL, seller's name, etc. If you post photos please post the front and back of all items in a size large enough for us to see details clearly.
Keychains are HIGHLY counterfeited because fakes are so cheap to produce and can be made in the tens of thousands. Coach keychains should always be authenticated especially since fakes can and do contain toxic materials like lead, arsenic and cadmium that are banned for that kind of use in most countries but are often found in cheaply made fakes.
If by "homemade" you mean keychains or jewelry made from pieces and charms of what are claimed to be genuine Coach items, many of those use fake parts too, and NONE of them, even if completely made of genuine pieces from genuine Coach keychains or jewelry, can ever legally be described or sold as "Coach" since Coach is not the final manufacturer of the item.
