B8913 Nickel Plate, Spring Bar Money Clip, Solid Brass-LL
The strength in the first 1-5mm of opening! We went through many rounds of sampling to make a better spring bar. What you should notice on ours is 1) the general strength of the spring from full open to full close, and most importantly 2) the strength in the first 1-5mm. A stronger spring action means your money is more secure.
