AUNHIRU White Blinds & Shades 21" W sku-18252153362

AUNHIRU White Blinds & Shades (sku-18252153362; UPC 130680899202) are cordless blackout roller shades listed at 21" W x 72" H. The stated actual shade size is 21 7/8" W x 72" H; the shade width is described as 1/8" narrower for inside mounting. For an inside mount, choose a size equal to or slightly less than the window width. For example, a 30 inch window calls for a 30" shade or slightly less.

For an outside mount, the guidance is to order 2-4 inches wider; a 34" shade is the given example for a 30 inch window. The package includes 2 sets of mounting accessories, with installation by foam glue or brackets and screws, plus instructions. The shade is described as blocking 100% of light for privacy, heat and cold insulation, light control and UV protection.

Its spring-loaded mechanism lets it rise or lower without a cord and stay in position. The fabric is 5/8" narrower than the shade width, so a light gap may occur. Inside mounting requires a window-frame depth of at least 1 2/5".
