Have ordered these spoons a couple times over the past few years. They really are sturdy and great quality I just hate that since the pandemic they went from $13 for a box of 1000 spoons to $27 but like everything else around us, the price has risen astronomically! Anywho, we’ve used them for Thanksgiving, Christmas and everything in between. My daughter uses them every night to scoop out cat food like someone else mentions. We have two cats and we don’t want to dirty up a spoon ever night for their nightly feeding when we divide a can of kitty food between them. I’ve used the spoons to mix resin, paints among other crafts and they’ve always held up without bending. Truly their worth the price but man it hurts the pocket when everything we buy right now has doubled to tripled in price now! (Even that dad-limb cat food! Lol) But if you can swing the cost I can promise you it’s worth it. They hold up well for hot soups and those big scoops of banana pudding like mine that is heavy! I’ve bought their forks once and they are just as good but we go through spoons so much more around my house.

Love these plastic spoons. Bonus - need no washing!

Material Type: Plastic

Excellent product, these spoons aren’t small for teaspoons like other brands. They’re strong enough for all types of food and never bend it break. Also, the price is right for so many spoons. I always by this brand.
