Shelled Drinking Spoon
Unlike our hands, which we primarily use to touch to feel, our mouth is more subconsciously touched by the products we use to eat/ influenced by a warm or cold environment.
Everyday objects that give subtle sensations to the mouth. The tongue and lips are very sensitive, but the experienced textures are quite limited in terms of ceramics and cutlery.
A shell-like outside that seems to be shedding. Making the user either more careful while using to protect. Or being disgusted by seemingly dead skin, protecting the content from being sipped away.
