I've used the Silkworm Fidget a couple of times now at in-person training sessions and found it to be a very handy little Fidget and good replacement for my more obvious hair twirling. I've never purposely taken a fidget with me to a training session before, and I found this to be a perfect entry fidget as a recently neurodivergent-diagnosed adult woman who is only just becoming aware of my stimming needs in certain settings. Plus, I'm in love with the oil slick colourway - looks stylish and funky. Very happy with my Silkworm.
