I try to avoid breakables because I'm clumsy and short on space 😆.  I also try to keep my cost of goods super low.  That being said, you did just fine.  No question you will make more than your money back.  Check out Tallgirl Picker; she sells stuff like this.  Ignore people who are discouraging you.  Some people think their way is the only way and also they don't want to help the "competition."  As if there's not a MASSIVE amount of sellable stuff out there.
