So you remove the manufacturer's and shaatnez inspector's labels before
the first time you wear a garment on Shabbos? Unlike a key pin, this
is permanently attached to the garment and thus batul to it.
According to SSK pg 215 RSZA says this is why extra buttons sown
onto a garment can be worn as well. (I am told RMF and RSYE hold
similarly.)

This was discussed widely WRT gloves. The gezeirah was about jewelry,
and few say it includes anything but. (This ties to the discussion of
whether qitniyos includes more than the original list of legumes.)

I knew there was a she'as hadechaq element, which is why I reiterated
both "Refuseniks" and "under the Soviets" to underline the context.

Tir'u baTov!
