New input: I bought these Trim Toenail Clippers because of "NJMOM's Review" above. NJMOM stated these clippers are "STRAIGHT" not "CURVED", WRONG, these clippers are CURVED! I emailed Farm & Home Supply Center for a "RGA Number" to return these clippers and never got one. I'll keep them but I'm not happy.If you want a straight cutting blade toenail clipper, these are not the ones. Get the Tweeezerman ones.
Solution:
Negative
