Nice, high end look, disposable
Color: Gold, Color: Gold
I hate to spend a lot of money on something that's just going to be thrown away, so typically buy dollar store disposable silverware for parties and gatherings. But every once in a while, you want something more upscale or high end looking. Enter this pricy but pretty plastic silverware. It is perfect for a wedding, anniversary, shower or other event where you want a nicer look instead of basic.
It is sturdy. You won't have to worry about it breaking as someone spears a bite of chicken. It looks great! There's only so much you can do with plastic ware but for what it is, it looks really nice.

Useful Yet Flimsy
Pattern Name: Plastic Spoons
Great for cereal, soups, easy to eat items. Too flimsy for hard ice cream or anything that needs a similar slice or scoop.
