Yep, those are seeds.

Why you got them? The leading theory from a few years ago was sellers getting fake positive reviews on their products by creating alternate accounts, "buying" the product and to fulfill the shipping status just sending some random leaked address a bag of the lightest, most cheap product they could send, just so platforms like AliExpress had an actual transaction completed allowing the review to be posted.

Do not plant foreign seeds or discard them incorrectly. You have no idea what that species is, and you do not want to be the one introducing a new invasive species to your local biome.

The label is in Chinese (simplified characters common in China) and translates as “100 rainbow chrysanthemum seeds”. I have no idea whether the contents are what the label claims.

Those little pip things on new tires, you gotta glue them on individually!

It says 100 Rainbow Chrysanthemum Seeds

They are most likely seeds. Whatever you do, DON’T plant them. If you’re in the USA, contact someone from your state’s Agricultural Department.

It’s a brushing scam. You’re now going to find that somewhere online, you have left wonderful reviews for their products.

Yeah, np, OP that says these are 彩虹菊花种子.

100 rainbow Chrysanthemum seeds

There is a kind called “Livingstone Daisy” we just translate it to rainbow😂

This is what's called a Brushing Scam.

I remember a few years ago on the other place that starts with "R", there were a bunch of people who were randomly sent seed packets from China. Big debate on whether they should plant them and if it would start the zombie apocalypse or not. Some planted them and it grew to be wildflowers...so far.

TLDR: seeds

You all are awesome. What's the best way to dispose of them?

Those are the seeds used to grow charcoal briquettes.

As other people have mentioned, please don't plant them. You have no idea what the seeds are and they could be invasive. As for why; no one's sure, but many people think it's some kind of weird customer rating scam. Like, they send you seeds and then use your info to make a fake review or something.

Rainbow chrysanthemum flower seeds

According to google translate + OCR on the label.

The Chinese reads that it's a seed for some type of flower. Unfortunately, I don't know quite enough Chinese to know what exact type of flower

At first glance I thought it was a bag of mouse turds. XD

I'm quite surprised it wasn't seized by customs with how blatantly obviously it contains seeds
