To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Received 49 silver tone, 49 gold tone that were 100mm...about 4 inches. 2 gold tone that we’re about 7.5 inches long and connectors for all but one chain. These are delicate chains and I would not use them for heavy weight or heavy use. I liked the longer ones, they actually made cute bracelets with a delicate feel and it inspired me to connect two of the keychains to make more bracelets with a single charm. Alphabet beads will fit over the chain an will work fine if you are making little keychain crafts; like cheer bows or name tag party favors.
