You may return most new, unopened items within 30 days of delivery for a full refund. We'll also pay the return shipping costs if the return is a result of our error (you received an incorrect or defective item, etc.).
You should expect to receive your refund within four weeks of giving your package to the return shipper, however, in many cases you will receive a refund more quickly. This time period includes the transit time for us to receive your return from the shipper (5 to 10 business days), the time it takes us to process your return once we receive it (3 to 5 business days), and the time it takes your bank to process our refund request (5 to 10 business days).
If you need to return an item, simply login to your account, view the order using the "Complete Orders" link under the My Account menu and click the Return Item(s) button. We'll notify you via e-mail of your refund once we've received and processed the returned item.
A $0.99 single tile of premium Arrowzoom acoustic foam — your choice of 4 shapes. Same density, same fire rating, same NRC as our 24-pack and 48-pack listings. You hold it, press it, smell it (no chemical smell — promise), and decide if it's the foam you want covering your walls.
Buying acoustic foam blind off Amazon is how people end up with a closet full of low-density import junk. Spend a buck, get the real thing in hand, then buy with confidence.
Still unsure? Order all 4 (4 × $0.99) and pick the one your room likes.

pyramid looks cool af
nice texture and better density than i expected
I wanted to feel the foam before ordering a full pack. This sample made the decision much easier.
I ordered the eggcrate tile for my home theater project.
Better to spend a little on one tile than regret a full order.
The sample convinced me. It feels sturdy and looks good on the wall.
