I ordered a bundle set and very disappointed.
Already two stems broke.
Third one broke too, and its white resin was bleeding.
Last one? Its stem didn't fill with white resin perfectly. (I think that's why it doesn't break.)
P.S. My Keyboard uses Cherry MX Red switch.
Conclusion : I ordered a bundle set, and it's all broken or defective.
Pink one
Red one
Blue one
Orange one
