One of the first questions I get asked by my customers is “How many charms can you fit in your Origami Owl Locket?” Origami Owl has 4 lockets. We carry a mini, medium, large and our newest heart locket. As a general rule of thumb, I recommend the following:
Mini Locket: 1-2 Charms
Medium Locket: 4-7 Charms
Large Locket: 7-12 Charms
Heart Locket: 4-7 Charms
With that being said, it really depends on the charms. Some of the charms are small (like the birthstones and pearl) and some charms are large (like the children birthstones and some of travel charms).
