First off, let me say this locket is GORGEOUS in person! The floral engraving is so delicate and detailed - way prettier than the product photos show. I bought it as a memorial gift for my niece after she lost her grandma, and she hasn't taken it off since.
The sizing was tricky though - the inside measures about 0.5x0.5 inches, so fitting photos requires some crafty cropping. Pro tip: Use the included clear plastic heart as a stencil before cutting your pictures! The chain feels decent quality, though some reviewers complained about durability.
Major bonus: It comes with a little heart-shaped photo protector inside (though fishing it out with a sewing pin was an adventure!). The packaging was disappointing though - just a plastic bag for a $70+ item? Come on Amazon!
Overall? 4/5 stars. Beautiful design that looks way more expensive than it is, but could use better packaging and maybe a sturdier chain option.
