Good strong forks
Number of Items: 500
I was looking for some good, strong forks for our office breakroom. Strong enough for Texas BBQ or anything else we might throw at them. These forks can handle the job! The spoons and knives are also very good, and I also order our10 and 16 oz paper coffee cups and lids from Comfy Package. Good products at a good price - hard to find!

Very Sturdy Forks
Number of Items: 500
These forks are very sturdy and similar in quality to Dixie heavyweight forks. They are hard plastic, not maleable, so they hold up well to hot food and can be used to "cut" foods such as lasagna. Good product.

Sturdy forks but be careful when opening. Amazon package and product box were damaged. A mess.
