Do all of the batteries come in a square blister package, or are they loosely placed in a standard business envelope?

They came in individual packets, but all attached together. You just tear off one packet along the perforated line to get a battery.

Ottima per il mio orologio Tissot

Perfetta per il ricambio del mio Tissot, senza andare dal orologiaio, funziona bene.

Hard to find battery works!

It was mailed to me via regular mail from Quebec. This hard to find locally battery worked to revive my almost 22 year old Swatch and I'm pretty happy about that. The expiry date on the package is October 2027 (it is now November 2025). Fingers-crossed the battery lasts at least that long.
