The Hudson's curved spine rests beautifully in the palm of your hand, while the built-in photo sleeves allow for easy loading. You can arrange the order of the photos yourself or click the “Auto Fill” button and presto! - it’s done. The Hudson 1 will hold 100. For the covers, we used our fine book cloth to coordinate with the rest of the Kolo collection. The perfect way to quickly, but elegantly organize your photos without using corners or tapes. Non-refillable. Also available in bonded leather. Archival / Acid-Free.
