Question: Are they non slip?
Document: Simple, easy to use, right sizes, comfortable hand holds, good pour spouts, easy to clean. They work and are not heavy. A non slip bottom would improve use but the price is right.
Great sizes. I use these bowls all the time. They nest well. I use the pour spout a lot. There is no non-slip rubber on the bottom so they slide on the counter. Good thing it has a nice grip. The largest one is the size you would use for cake batter or to make a 36 cookie recipe. The smallest size would be great for carrying a little fruit snack into the living room or whipping up just one tuna salad sandwich.
Lightweight, Non stick, attractive, and affordable.Requires a minium of space.Easy pour feature.My regular bowls are ceramic and quite heavy, so I am pleased.
I love this bowls. They look better than in the picture. The bowls are made from solid plastic, they don't bend, or lose their shape. The colors are gorgeous, a little shiny and you can wash them very easy. The rubber ring at the bottom don't allow them to slip, and the capacity/volume of each it is perfect for cooking for 2-4 . Love them!
I love these things, truly. Easy to clean, non-staining, useful for a million kitchen applications, great price point. I prefer these to the metal mixing bowls that I have when I need to cook in the kitchen and not wake anyone up with too loud of a noise clanging the bowl bottom with a whisk. The curved edge is great too to control pouring or dripping.
this purchase was part of a bulk purchase for my fiance for christmas. though they were a day late in arriving they made it in time for christmas. my fiance was very pleased with them. which in turn made me very pleased with the purchase.
this mixing bowl set are a great help in the kitchen.. they can be used for different kinds of things, easy to wash as the grease goes off very easily..
these are nice mixing bowls, easy to clean and stackable so it takes up less space . nice rim around the bowl easy to hold on to and tapered for easy pour.
these are great, they have a place to hold and a place to pour and they come in the perfect sizes. they are hard plastic but mine still look new and i have used them over and over. I would buy more of these in a heartbeat.
the only thing I wish is that they had a bigger one like the ones that I am replacing  but am sure that  they will get a good workout.
Answer: No they are not. They are smooth plastic all over.
