These beautiful ornaments are a fun way to bright up any room. Each ornament is made with resin , glass beads and 20mm crystal. Accept option A, that does not have any glass beads attached. They make a great gift for any crystal lover! Because they are made much thicker than normal ornaments, they can handle some sunlight. DUE TO IT BEING MADE OF EPOXY resin, resin is known to soften when in extreme heat. Not to worry it is an easy fix, just place on a flat area and let it cool. I personally hang my suncatchers in my widow where they get a decent amount of sunlight and never had any issues. If you have any questions or concerns, please do not hesitate to contact me . Customer satisfaction is my number one priority.
