Your left thumb and right thumb may differ slightly in width, curve or cuticle shape.
Do not copy sizes automatically
Test each finger rather than assuming the same size number belongs on the opposite hand.
Daily use can affect fit observations
Dominant-hand nails may experience more leverage and reveal a marginal fit sooner.
Keep ten separate notes
Record all ten fingers individually for the exact product.
Recheck when changing shapes
A size that works in one mold may not transfer to another.
