Great value for the money!!
They are not as stiff at the bottom of the handle where it’s connected to the actual spoon as others but I have been using them daily since i received my shipment some time back and none have broken. I am very satisfied with this purchase for a great price! Having so many (1000) spoons is one of life’s tiny pleasures of knowing I will not have to worry about ordering my plastic spoons for a very long time. Compare box of 100 for $3.89 or 1000 for $9 98! Easy choice for me.

Fine, but bag was open…
The spoons are fine and what I expected for a great price, but unfortunately, the plastic bag they were in was wide open in the box so I had to wash all of them… What a pain in the butt that was… Hopefully that’s a one time experience.

They're ok
These were very affordable; however, they are quite bendy so it's hard to use them depending on what you are eating.
