[Colour changing] True Crime Tumblers

Material: Glass cup and straw, bamboo lid with rubber seal

Capacity: Approx 550ml

Serial killers, dead bodies. Know a true crime fanatic? These tumblers are perfect for staying hydrated while binging your favourite crime shows (tried and tested, trust me). Parts of the tumbler turn red when filled with cold water (or chilled red wine, if you get my drift).

Each glass tumbler comes with a lid, straw and straw cleaner.
