NICETOWN White Blackout Curtain Liners
Features: READY MADE. Includes 2 panels of blackout curtain liners with bonus hooks. Each panel is 27″ wide; same back material as front for a polished look. High-performance fabric blocks 85%-99% of light and UV rays, and offers noise reduction for better TV viewing or sleep. ENERGY SMART design balances room temperature by insulating against summer heat and winter chill, protecting furniture from sun damage.
Best for: Home bedrooms or media rooms needing reliable light control and quieter environments. Choose this if you want an easy, ready-made liner that enhances existing curtains without complex setup.
Caution: Size should be matched to existing curtains; choose the closest fit to avoid gaps. Triple-weave fabric provides solid blackout but color may appear lighter on certain fabrics.

Best for: Renters or DIY enthusiasts seeking a low-commitment installation that can be moved or removed without tools. Choose this if you want a reusable, no-residue film with strong light-blocking performance.
Caution: Edge gaps can cause light leakage if not applied carefully. Not ideal for certain double-pane window configurations.
