Looking for reflective material for still life set up

As the title suggests-- Any idea of what I can use. Needs to be thin, flexible and reflective somewhat like a mirror. Looking mainly for black or smoky gray color, also maybe a silver. Have looked for mylar and acrylic material, but have not found anything larger that 12x12. Would anyone know of a company or manufacturer of products like this? Thanks for any help.

Rosco makes quite a few materials handy for lighting.  I usually just got to BandHPhoto and search on Rosco to find things like this

Foil ?

Thank you all for your suggestions. Will look into all of them. Rosco looks promising, but I don't need or want to pay for a 50 foot roll. Need more like a 4x4 or 5x5 pieces for table top photography. I am going to see what Hobby Lobby has available.

Metallic gift wrapping paper, attached to support. I have used scraps of this for fun when lighting jewelry and other small objects for macro. It comes in a huge variety of colors.

Silver conventional pop-up reflector for photography.

Silver bubble-wrap ("Reflectix") insulation: an example, comes in many sizes:

Emergency "space blanket" costs about $4.00 at an outdoors store - of course it comes in one color, silver. It is a good idea to have one of these in your car, if you liver where it gets cold. If you plan to re-use a lot, you might also consider the durable version. I keep one of these in the car for emergencies, and have also used it for an unattached sleeping bag cover when car camping in cold weather - easy to push it to one side.

Thanks Nancy. This papermart out fit may be very promising.

Look into aquarium backgrounds. They often come one side black and one side blue. 4x5 may be a bit hard,  but 2x4 readily available.

Here is an example: https://www.amazon.com/Vepotek-Aquarium-Background-Ocean-Double/dp/B00U1RDYS2

Thank you for the info. I would not have thought of that in a million years and I used to have aquariums in my younger years.

Let us know what you end up with.  And of course, post samples.
