Great Bulk Pack of Disposable Spoons
These is a nice bulk pack of disposable spoons, and at a great price value. They are light weight, sturdy, BPA free spoons that conveint and safe to use everyday. My daughter is finishes her 9th grade school year in a couple of weeks, and when she is done we are have a small ice cream party. Which, is why I got these spoons. They will be perfect for the party and clean up will be very easy. Overall, I am happy that I got these spoons. I would recommend them to anyone who needs a bulk quantity of good quality spoons, and I don't have anything bad to say about them at all.

Good price
For a thousand spoons, you can’t do better. It’s a great value for the price. They’re not the most durable spoons, but they’ll handle a family reunion with ease. If you need them for the office or a reunion, or you just don’t want to do dishes, you really can’t beat it. Eventually I’ll buy them again.
