Most of these first ones probably date to the early 20th century, some are older, some a little newer. The black writing is the type or size of needle, for example, 'silk', 'tsumugi' ( a type of silk), 'small cotton', '4-2', '4-4'. I'm not sure how the sizes work.

Clover has been producing needles and other sewing accessories since the 1920's. I sell Clover needles in the shop. Here are three generations of Clover needle packets.

It's interesting and a little sad to see how much packaging it takes now for 6 needles compared to a small piece of paper for 25. In the old packages the needles are first wrapped in a small piece of foil and then simply folded in the paper. (I package sashiko needles for the shop and use this method - it's easiest and most economical).
This is an old shop display box for 'Clover top quality sewing needles' - '1 packet 10yen, futon needles 20 yen' :
