Dreamscene Blackout Silver Curtains Insulated Curtain 2 Panels Set 46×72 (117cm 183cm) – Sold/Shipped by OnlineHomeShop

I saw someones just posted a £12 for Argos but for a 54 inch drop. I was surprised to see this length going for 11.99 so I just ordered a pair myself. Theres not many colours to select from at this price point though. Says its the lowest price in 30 days (previously 16.99).
Hopefully it can insulate the room.
