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

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

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

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 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.

Received 50ft roll today for indoor horticulture. Arrived undamaged and roll wrapped in protective plastic as it should be.Concerned about hot spots, I cut the appropriate size sheet (4’ x 3’), grabbed from back side of film and crunched it into a ball. Unsatisfied with the amount of wrinkle, i scrunched it 3 more times. Using 4’ x 3’ project board I then spread out the sheet and attached with metal duct tape. Checking again, no streaks or damage to the business side of the film.To finish the first panel on my homemade grow, I attached to the frame with 3/8” staples.At this point, I’m pretty happy with the Mylar as it shipped undamaged and no problems with streaking/rub marks/thin coating even after I went to town on getting the right effect from wadding and crunching the heck out of it.After I’m done wrapping the grow, I’m going to film a couple of West facing bedroom windows against the Arizona sun.**as of this post, I have not checked entire roll, to confirm I received a full roll of finished product**

Thick and durable! Very happy!

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