Is the current price of slime justified?

I don’t have an established opinion yet. I like to be as informed as possible before deciding on what I think about something. I’ve noticed that most major slime shops are charging between 16-19 dollars for slime plus or included shipping.

At the cost of materials and labor, is this justified?

I love making slime and granted my slime isn’t as renowned as say MOMO slimes or OG slimes, but to me 20 dollars for a single slime seems a bit excessive. I’d like to think that if I ever reach that level of success in this business I’d like to keep my slime as affordable as possible especially since not all children or parents can afford to splurge that kinda of money.

What’s your opinion or reasoning?
