Vintage original PYREX 4.7 inches bowls (5 pcs) milk glass with Band circles

There are 5 original vintage milk glass Pyrex. All marked pyrex in the bottom .. each measures approy4.7 inches in diameter .. there are “ bands” or circles .. dark Bordeaux color .. some of the bands have west or color fade I think this is due to manufacturing. Please see pics.. do not detract at all I believe these were not used BUT to be safe the slightest wear .. these are old vintage Pyrex not brand new
