To which I asked about the shaatnez checker's plumba. Or extra buttons
sown onto the garment.

Or, for that matter, why cloth is different. AFAIK, a manufacturer's
label or one from a shaatnez checker sans plumba is only batel because
it was made an integral part of it with stitching. Unlike something
pinned on, like a non-ornamental key.

Well, since the SA says that mei'iqar hadin "shema yishlof" doesn't
apply to gloves, yes. The MB says that because we don't have too
many reshuyos harabbim deOraisa today, even he doesn't advise being

And Shemiras Shabbos Kehilchasa says the same about a non-ornamental
watch, explicitly stating that an ornamental one (which you would
wear even if it weren't working) is under the original gezeirza, since
it's a tachshit.

Thus, there is reason to hold that the gezeira only includes those
situations that the gozerim included, no more.

Gut Voch!
