Buying Guide: Key Considerations for 20×20 Shadow Boxes

- Protection: Look for UV-protective acrylic and acid-free backing to minimize color fading and preserve textiles, paper, and photos.

- Aesthetic coordination: Black frames pair well with contemporary spaces; white frames suit bright or minimalist walls; wood tones fit rustic or classic interiors.
