Petaholic 100% Blackout Curtains — Cut-to-Fit No-Drill Window Shades 79×57 with Adhesive Tabs & Travel Bag

Petaholic 100% Blackout Curtain is a cut-to-fit, no-drill window shade that blocks all light and provides portable privacy for bedrooms, travel, dorms, and media rooms.

These blackout blinds use a silver-backed fabric engineered to stop sunlight and UV rays while sealing tightly at the window edge for full darkness and privacy. The sheet can be trimmed to match odd window shapes, installs in minutes with included nano-adhesive stickers and Velcro tabs, and packs into a small bag for travel. It’s designed for people who need an instant, non-permanent blackout solution without hardware or tools.

How does it achieve 100% blackout?

The curtain is made from dense blackout fabric with a reflective silver coating on the back that prevents light and UV penetration. The design intentionally overlaps the window frame so no light gaps remain around the edges when installed correctly.

• Silver-coated reverse blocks sunlight and reduces glare.
• Cut-to-fit sizing lets you extend material beyond the frame for full coverage.
• Adhesive stickers and Velcro tabs secure edges to eliminate light leaks.

How simple is installation and removal?

Installation follows a quick Measure > Cut > Connect workflow—no drilling, tools, or permanent fixtures required. The included nano-adhesive stickers hold strongly and are formulated to remove cleanly, while Velcro tabs help keep the curtain taut and edge-sealed.

• Measure window, cut curtain slightly larger for overlap.
• Stick adhesives to clean, dry surfaces and press curtain in place.
• Use Velcro pairs to tension edges for an improved blackout seal.

Can I use this for travel or multiple rooms?

Yes — the fabric is lightweight and foldable, stored in the supplied pouch for easy transport between hotel rooms, rental properties, cars, or temporary living spaces. It works across bedrooms, media rooms, dorms, RVs, and short-term rentals where a non-permanent solution is preferred.

• Portable storage bag included for travel convenience.
• Suitable for irregular window shapes thanks to DIY trimming.
• Non-permanent adhesives avoid damage to rental property surfaces.

What care and setup tips should I follow?

New fabric may have a faint odor or creases from packing; airing it out for 1–3 days removes smells and low-heat ironing (on the non-silver side) reduces folds. For best adhesion, clean and fully dry window frames before applying the nano stickers.

• Unfold and air the curtain for 24–72 hours to dissipate odors.
• Iron on low heat on the fabric side, not the silver backing, to smooth creases.
• Contact seller if any accessories are missing from the package.

If you want an adjustable, reusable blackout solution without drilling holes or committing to permanent window hardware, this curtain provides flexibility, strong light-blocking performance, and easy transportability.
