These are nowhere near as good as the crystal suncatcher kits of my childhood, where you melt the crystals in the oven (in a metal frame) to create a glass-like effect. This trinket box itself is nice enough but you glue the crystal pieces into the plastic box, and the effect is kind of tacky because the crystals are tube-shaped and don't look finished. Crystal-shape crystals would be far better, and sit neater in the frame. The glue is PVA so if you get it wet the crystals will fall out.
