The identical marker I of Clover in teal and orange (made in Japan). They are a joy. Smooth surfaces everywhere, soft plastic, always easy on and zuklickbar, in use for years. Unfortunately, I've lost quite a few, yet merh colors are to be welcomed, so I bought the wool shop which (look like this) from Knit Pro - the material is a little harder, but they work very well. At closer look, I discovered on the plastic surfaces a tiny "Made in China". Explains the difference, is in use but not essential.
And then there are several similar, nearly identical formed parts in many more colors, but ... you would have to touch and compare. (Maybe it's also good here)
