That’s a classic “nostalgia” image.
These are old-style dishwashing liquid bottles, the kind that were very common in kitchens in the 1990s and early 2000s. The design is very recognizable: a curved “grip” shape in the middle so you could hold them easily, with a small angled spout cap on top.
Back then, brands used this ergonomic shape a lot for products like:
- Dishwashing liquid
- Liquid hand soap
- Sometimes shampoo or cleaning detergents
