Everyone loves a little darkness
This story reminds me of books by Philip K Dick and Ray Bradbury. Sci fi dystopians that examine the harmful impacts of technology on humanity and how the pressure to conform brings out the worst in us. I'm a big fan of those stories, I bet you are, too.

I think this story would be far edgier if you cut out the main character's narration and focused on objectively writing about what's going on around him. Don't tell us what he's thinking. That would make it more tense and creepy, like the style Black Mirror uses to unsettle viewers when the main character is thrown into a dangerous or unusual scenario but doesn't always react clearly to it or simply doesn't let the viewer know what they're thinking. It's a less tiring way to write, as well, it helps keep paragraphs nice and short.
I also think the dialogue needs some more work. It comes across as being wooden, something that you can fix by making sure you read character's speech aloud after you type it and then take a moment to see whether it sounds natural to you. That would help the story to feel more plausible. Another note: I recommend you revisit the product description because most companies would never insert the word "toxic" into a statement regarding their own product, even when trying to describe it positively (minus tiny print "non-toxic chemicals / non BPA descriptions). It seemed like you were trying to unsettle the reading by including that word but it isn't subtle enough.
The ending makes the story, I loved it.
All in all, a pretty cool story. I look forward to reading more of your work.
