VIVOSUN Highly Reflective Mylar Film Roll 4FT x 50FT for Outdoor Grow Room Indoor Decoration Aluminum Paint Coated 2 Mil Silver

Perfect for putting behind my grow lights on a shelf, and blocking 98% or so of light from going outside!I was worried about durability/ not being reflective enough, but it exceeded my expectations.It is very thin/ light, but inside it looks like a slightly distorted mirror (because it's not perfectly straight). It might be slightly less bright than an actual mirror though, but I wasn't looking for a perfect mirror.At night, before my grow lights were lighting up the entire backyard. Now with this behind them, you can barely see through the film at night unless a couple feet away (all I have int he room are the plants, so no need to close the blinds)!If you're looking for a near (but not perfect) mirror surface, that's light, thin, and durable enough for how thin it is (I accidentally rubbed it against the metal shelf, and the surface didn't rub off), then this is great!NOTE: One side is much more reflective than the other (like one is 80% vs. 98% looking). The inside of my roll looks like a mirror, whereas the outside looks closer to aluminum foils reflectiveness. So make sure you pick the mirror finish for reflecting light!

I have not loved a product of its kind like I love VIVOSUN in my entire life. This product and I were so meant to meet! The first photo shows the space prior to VIVOSUN. With this product you can be endlessly creative and playful. (I should have gotten the biggest roll, but it's okay, I will get more when I run out because I keep finding things that VIVOSUN will make far more beautiful and enjoyable.) -- The third photo shows two small filing cabinets that I got as base for my glass top desk. I could not stand the idea of having two big objects obstructing the light and view; the solution? Cover them with VIVOSUN. <3 <3 <3 The second photo shows the door, which used to be horrible; it now is artistic, beautiful, reflective of light and enhancing the sense of space, like everything where VIVOSUN goes does. I couldn't possibly love this film more. I would cover an entire wall with it in a room, but maybe in the future :-). I cannot say thank you enough for making this awesome product and also for making it affordable.

Good quality roll of mylar and great price for a 5 x 25 foot roll. Shipped quickly in an Amazon branded box

I have created a mirror dimension in my closet. A wrinkly one. It is reasonably tear resistant but tape the staples to keep tears from appearing if you use them. One thing worth noting if you’re building a tent for photoperiod plants is that it’s not opaque - you can more or less see through it even if it reflects 90+% of light. Blackout curtains can be found cheap, you might consider it for sides prone to light leaks.

It's a cheap but effective prop for my photography. Gives nice effects.

Very good result

I bought this for an art project but it is much too small

Great quality, wasn’t slippery, not easy to tear, and super long n pretty
