Beatrix and Luca Lux Boxes are handcrafted with the highest quality velvet materials and ultra plush foam. This results in a gorgeous and luxurious texture inside and out, and creates a perfect cradle for either his or her (or both!) ring bands. Plush foam fits from 1mm up to 10mm ring bands. At B&L, we are a small family-run business based in the USA and are committed to your satisfaction. If you have any questions or concerns, please feel free to ask!
