Gazzew Springs - 63.5g/17mm
The best weight. The perfect length. Made by Gazzew.
These long springs are the jack of all trades - linear and tactile switches will both pop when you swap these in. These are made from the same Korean spring steel as the other guys, without the insane price tag. Each pack contains at least 100 springs.
These are comparable to a Slow II, and in-between a Long and XL from other spring suppliers.
