Old Card of 36 Tiny Vintage 4-Hole Pearl Off-White/Ivory Shell Buttons 8mm #OT-118

Tiny vintage jewels from sewing history, hand-sewn onto cardboard cards. No markings; these are from who-knows-exactly-when. We were told 'antique'.  4-hole, 8mm buttons; around 5/16" diameter and wafer-thin. Each card is about 2.5" long x 1.25" wide, with 36 delicate, ivory pearl shell buttons. (Not bright white). Price is for one as-is card; we have 5 available. They are probably quite old; most of the buttons seem to be in good condition but a few have small chips, as the photos show. If only they could talk...
