I use these for my center weights when doing kumihimo braids. Perfect for my use and adding or reducing weight if needed. Great size and functional for many things for it's adjusting

Looks fine
They look like they will be fine. I haven't used them yet. Smaller than I thought they would be, but thats good.

Don’t. Just don’t
Waste of money. Waste of time ordering and definitely a waste of time returning. These weights are very tiny. Not suitable for fabric weights

Ne tient pas tout à fait le tissu en place. Je dois en mettre plusieurs pour avoir un minimum de stabilité de mon tissu.
