Yeah that's what I liked about it too. I'm on a break from vaping right now but once I start up again I'll buy that thing and see how it works.
Only thing I'm worried about is that it might be too big. Hard to tell what the size is online.
Also saw stuff like this on Amazon that I might checkout: https://www.amazon.com/Kbsing-Flexible-Silicone-Sculpture-Shapers/dp/B011KQIUF4/
These are the exact ones that I used, though they appear to be unavailable now. To answer your question though, according to the picture I use size 0, the black tipped ones.
Here are some that appear to be in stock.
Alternatively, you should be able to find these at most arts and craft stores (Michaels, or Hobby Lobby, if you're in the US)
Also just because I feel it's relevant, a mini painter (Trovarian Miniatures) that I follow on YouTube just happened to upload a video about sculpting and the appropriate tools for the job, wherein he mentions color shapers. You can check it out here!
Hope that helps!
Thank you! that means a lot to me. Simple sculptures are just as nice as complex ones though! If you need help making complex sculptures though, there's a lot of clay tools that help with detailed work. I religiously use clay shapers for every single sculpture I do. Every. Single. One. If youre having trouble with detail work that doesn't just look like flat chicken scratch on the clay, clay shapers help give some subtle depth. Use the tip of the round ones and roll them onto the clay to give depth or blend clay together.
If you're having trouble with keeping proportion symmetrical and correct, I recommend buying a clay conditioning machine. I also use this thing religiously. While sculpting Sans' head, I wanted to keep it very symmetrical. I just flattened out the clay in the conditioning machine and cut out equally sized pieces in it. Placed them on where the bottom jaw was supposed to form gradually while using the clay shaper to blend them in. For the stitches in his hoodie and such I just used a clay needle and drew them in at about a 45 degree angle.
If clay tools still don't help, then I'm sorry to say but all that I know of that can help is practice. When I first picked up clay for a high school class I had to sit and make dozens of 1" human faces out of the Sculpey and it was extremely painstaking practice. That was about 3 years ago and my face sculpting techniques still aren't terrific. But they have improved! If I hadn't sculpted all of those faces (which in my beginning stages couldn't stop becoming old men/women faces, don't know why that kept happening) I wouldn't have been able to sculpt Sans' face the same way I did now.
Try sculpting a ton of faces if you want really rigorous practice! A lot of the techniques sculpting faces apply to other sculpture subjects anyway.
