Please note we advise caution when buying from eBay, some reputable brands have been counterfeited and it can be very difficult to know what you are getting. Moby, Ergo and Beco all have known fake versions. See here for an excellent article from the South London Sling Library
about fake and illegal carriers.

Safe buying – we recommend only using the “goods and services” option when paying for anything with paypal, to ensure protection should your purchase be unsatisfactory for any reason. Always be cautious and check seller feedback before parting with your money, and remember, buyer beware!

Please read this helpful article from the West Yorkshire Sling Library on second hand buying, and remember, every sling library will try to help you make the most of your carrier, as much as they are able.
