Necessary
Size: 1 X Pack of 180
Let me pre-empt this with I’m single and travel a ton, so dishes and silverware don’t suit my lifestyle (don’t judge me I’m here to help) so these can be used just as well as stainless or silver cutlery. Very durable. Beware that they may show up with the lid not in tact, causing a small or moderate amount of them to bridge the container. Still, very much worth it.

High Quality
Size: 1 X Pack of 180
I'm so happy with this purchase because this set is very high quality and sturdy. I also like the container it comes in because it's very convenient to set out on a table for guests. I don't quite understand why there are less knives than forks because if you use this for a get together, most people will take one of each, so then you're left with a lot of forks. But then that container comes in handy for storing them! :)
