Needless to say, this is what happened.
I contacted the seller and let her know what happened. She had less than 10 feedback and was new to selling. I let her know you can only ship First Class mail if the package weighs 13 ounces or less. I showed her the pictures and stated how disappointed I was that they broke. I asked her if she had any others she could replace them with. She did not and refunded me $5. It was nice of her to give me the refund but had she just bubble wrapped the thimbles, this could have been avoided.
