This MAC Small Eyeshadow comes in a single pan format. To set up, you may place it into a refillable MAC Pro Palette (sold separately) for convenient storage and organization. Ensure the pan clicks securely into place. It is compatible with most standard eyeshadow brushes. For optimal performance and hygiene, always apply eyeshadow with clean brushes. Clean your eyeshadow brushes regularly with a gentle brush cleanser and allow them to air dry. Store your eyeshadow in a cool, dry place away from direct sunlight and extreme temperatures to preserve its texture and pigmentation. Keep the lid tightly closed when not in use to prevent drying or contamination. Avoid dropping the product, as it can cause breakage.
