Pieces chewed off
Color: white & green
My Aussiedoodle loves it. I throw it down the hallway, it bounces crazy, and he chases it. The only complaint is that he can't chew much of the ball part. So now I have to have it put away and brought out for special playtime.

Exquisite! Durable! Beautiful!
Style: Gold, Size: 180PCS, Style: Gold, Size: 180PCS
I bought & used these for a Senior Adult banquet event. They were durable and beautiful. The exquisite design complimented the plates and the round gold placemats I used for the centerpieces. Lots of favorable comments from those attending the banquet.

Pretty color
Style: Red, Size: 180PCS
I am given this five-star based on the looks of it because of that it arrived too late and didn't arrive until the day of my party. I had already purchased some other plastic wear to use. I wish this would have came sooner because it would have been beautiful for my Christmas party. I am going to store it for next year's Christmas party and see if the color fades at all. If the color fades it may turn it into a pretty pink who knows. All I know is the plastic ware seems very sturdy and is gorgeous.

Gorgeous and elegant disposable silverware!
Style: Gold, Size: 400 PCS, Style: Gold, Size: 400 PCS
I bought this gold silverware pack for my parents' 50th anniversary party. The gold is a nice, pleasant shade and not too yellow or brassy looking. Nice and shiny. I had originally bought a set of plastic ware from a different retailer and ended up returning them to get these- the other ones were a dull, almost brownish gold and didn't look nearly as nice. I think these ended up being $3-4 cheaper anyway and we got more in the pack.
We had a party for abut 60 guests and there were plenty of forks, knives, and spoons for lunch service, coffee stirring, and cake for dessert. I have quite a few left over to use for something else but this pack gave me peace of mind that we wouldn't run out and our tables would look great.
See photo for mock-up of our place settings. The silverware goes well with other tableware, most of which is also from Amazon sellers (except the gold charger plates from Dollar Tree and the paper plates/napkins from Costco).
