For me, it’s an electric toothbrush. It doesn’t matter if you go with Sonicare or Oral-B, once you start using an electric toothbrush, regular toothbrushes don’t ever feel like they clean your teeth properly. The smooth plaque-free top layer of your teeth that you can feel after using an electric toothbrush can’t be replicated with a regular toothbrush.
The picture is pretty self explanatory imo, its an ice cube box that makes proper ice cubes, comes with two trays so you can make a whole bunch at once, the box acts as convenient storage so you can prepare a ton of cubes ahead of time, and the lid works as a tool for getting all the cubes in a tray out at once, without having to press them individually like on some other solutions.
The picture showcasing the well thought out design was preferable to posting a link or naming a specific manufacturer, since its a generic design you can find on Aliexpress or other sites from various brands. It should be easy to find by just looking up “ice cube tray box” or something.
A picture gets the idea across more easily than describing the product I think, and leaves less room for interpretation.
