25 acoustic foam panels/tiles for studio sound-proofing (Seven Dials BN1)

Set of 25 black acoustic foam panels/tiles for studio sound-proofing with pyramid shapes

Each tile measures 25cm x 25cm x 5cm

They're all in brilliant condition (basically like new), with just some very minor marks on the back (wall-facing) side on some of the tiles, which wouldn't be visible once they're up anyway

The tiles are very lightweight so can easily be fixed to the wall just with double-sided tape
