Great for everyday use
We use these daily. I buy the complete set then boxes of each to refill. Very sturdy utensils. Size is perfect. Very easy to clean to use after dinner for deserts. Knives work very well and fork ends are sharp enough to stick in your food to eat. Only brand we use now.

Great quality!
These are every bit as good as the more expensive plastic ware. They’re thick and sturdy. I particularly like the cutouts in the handle. They’re easier for me to grip and keep ahold of. Extremely happy with this purchase.
