Yes you read that right! Scratch and Sniff wallpaper is an actual thing.
The Flavor Paper line has three different patterns and smells-bananas, cherries, and citrus — that come in a variety of different colors. Looking into the specifics they found a water-based adhesive with micro-encapsulated fragrance oils. The stuff’s hand-applied to paper, and when you scratch it, you pop the capsules and release the smell.
Designers and celebrities have jumped straight on the band wagon in using these papers in homes. Tommy Hilfiger installed each of the ‘Scratch and Sniff’ designs in three bathrooms of his Miami mansion.
