Phone cases used to be forgettable. Rubber, plastic, purely functional. Today, they are as much a style statement as a handbag or jewellery. They are curated, styled, photographed—and in the right hands, they carry personality.

Enter WONHEE of rising K-pop girl group ILLIT, whose collaboration with CASETiFY is less a celebrity tie-in and more a reflection of how fashion lives in objects. Launched alongside the Samsung Galaxy S26, the collection embraces the motto: opposites attract, style connects.

WONHEE’s designs channel Y2K energy with a contemporary twist: pixelated textures, watermark graphics, bows, hearts and stars in hazy pastels grounded by cream and black. Playful but considered, nostalgic yet modern.

The collection’s brilliance is in its modularity. Magnetic-compatible cases, Snappy™ Grip Stands, and a Metallic Bow Phone Charm invite layering and personalisation. As WONHEE says, styling a case is like layering an outfit. Style is no longer worn—it is carried, curated, and on display at all times.

With prices from $78 SGD to $114 SGD, the collection is accessible without feeling disposable. It is not just tech protection—it is an extension of identity, a statement that fashion now travels with you, literally, in the palm of your hand.

In Singapore, shop the collection at CASETiFY stores in 313@somerset, Bugis Junction, and ION Orchard.
