Do all Fendi bags have a hologram?

No, not all Fendi bags have a hologram square with the serial number. This technology was introduced in 2004 but was retired by 2011 in favor of more sophisticated technology after counterfeiters were able to copy it. It’s important to purchase from a vetted seller or vendor to ensure authenticity. While Fendi has at times inspired knockoffs, 1stDibs partners with only top-vetted sellers to offer authentic pieces that come with a buyer protection guarantee.
