Nice n Robust
Material Type: Plastic
I’ve been buying these spoons for at least 5 years. They were the best before, and they are the BEST now. Other companies on Amazon sell similar spoons for a much cheaper price. They assert that their spoons are “heavyweight” spoons. Whoever, when you try to use their spoons to get yogurt out from the container, they fold like paper. These companies should be banned from Amazon.
