Wow, super duper fast shipping! I ordered these in the late afternoon on Wednesday and they were delivered by Thursday morning. Enough about that. I wanted this set because I'll be doing some pencil sketching in the next week while recovering from surgery. I love how there's two ends to each tool. One side is a firm, felt like material for blending and the other side is a soft sponge like material for use with shading and creating natural shading. There are two sizes, so six are smaller for getting into very small, precise spaces and doing light touch work and then the larger size for covering larger areas of your work. They feel like a nice weight, not too heavy for when you want to use them for extended periods of time, say on a large piece of artwork. They feel durable and they don't twist around while using them for shading. You have complete control over how you use them. I purchased the set in blue of 12 pieces so I can see having these for a very long time and getting use out of them not with just pencil lead but with other mediums as well, such as water colored pencils and charcoal. These are a very versatile type of artist's tool and can be used with just about any medium you want. They're comfortable in my hand and feel sturdy enough for both soft touch and hard touch. They're also easy to clean with hot water and a dab of soap. I think it's a great value and I wouldn't hesitate to recommend them to any artist, beginner or experienced!

These are sturdy, well made blenders. The white tip is much like a compressed paper stub blender, and the dark foam end is a very soft spongy blender that’s great for feathery, ethereal blending. Press too hard with the spongy end while using pastel chalks will basically remove most of the chalk. But a very light touch can give exquisite results. I have not had the same issues as some other reviews with the white ends getting imbedded into the metal handle, and I received all 12 pieces. My set came complete, and it’s all top quality. The only thing that would make this set better would be a nice case to keep them in. Other than that, I think these are perfect for chalk, charcoal, graphite, and maybe creamy-leaded color pencils (like Prisma brand), although I haven’t yet tried them on colored pencils. Recommended!

Why did you pick this product vs others?: The white felt end is great. It is firm and blends well. The small size black sponge side works fairly well. But the large black sponge size is very very squishy and floppy and does not work well. For the price, the white sides are worth it. I have not yet used them enough to see how they clean. If they clean easily it will stay a 4 star. If not...

I know these don’t look or seem like quality art supplies, but, they are fantastic for blending and smoothing colored pencils, for shading, and smudging rough edges. The white end blends and smooths, while the black end smudges. These are a go-to on my drawing table; I have not found anything that works as well as these unique tools.

My expectations were low, and these about matched them. Looked like a gimmick, felt like a gimmick while using. Both sides are harder then i expected, neither really smeared well, just buy a tortillion. For the price I’m not complaining, but a q tip, tortillion, and paint brush keeps these out of my shading rotation, they don’t really do anything well, and don’t cover any niche for me to justify them in my travel kit. May be worth trying for the price, but for me not my cup of tea in use.

I've only been using these for about 2 weeks but so far I love them. I was going through the paper tortillions fairly quickly and wanted something that would last longer. They're working great for shading on the zentangles that I've been drawing lately. I haven't tried washing them yet, and not sure just how long they will last, but so far, so good.

These are pretty nifty. I started with the plastic ones with the replacement sponge ends. Those aren't great. THESE are easy to use. And smoother. The black end is more of a burnisher. Blends somewhat, but burnishes what you've already blended or already laid down. The white side is rougher. It will blend. But don't press too hard because it is rougher and can tear your paper. It's made for light pressure use. Use the white end first, then the black. You can clean the ends as well. Clean the black end with a damp cloth, the white end you can scrub a bit harder or use an eraser on. You don't absolutely need these, but they do give you another way to add personality to your art.
