The 25 is the roomier of the two Backpocket sizes, and that extra depth changes what it holds: a full inch takes sunglasses, a compact and a phone rather than flat essentials alone. Plain Swift makes its case on hand alone, the softest calfskin in regular Hermes use, with a fine grain and a light sheen that shows the leather instead of a pattern. That softness is the trade-off, since Swift marks more readily than Epsom or Togo and every example has to be judged on its surface. As the pouch that organises the inside of a Birkin or a tote, this is the size most owners reach for first, and it is the one that turns up least often with an unmarked face. Grade B - Excellent, with a dust bag. Maison de Beaubigonne authenticity guaranteed. Dimensions: 8"W x 6.5"H x 1"D
