What are the differences in thickness and card capacity between the Small and Thin options of the Kettle Zipper Wallet?
When purchasing the Kettle Zipper Wallet, the customer is trying to gauge the difference between the two size options based on the number of cards they usually carry and their preferred volume.
The Small option has a thickness of 3.5cm and holds 20 or more cards, while the Thin option is half that at 1.8cm thick and stores 10 or more cards.
Between the choices for the Kettle Zipper Wallet, the Small option holds 20 or more cards at a thickness of 3.5cm, and the Thin option holds 10 or more cards at a thickness of 1.8cm[1][2]. Compared to the Small, POSTALCO reduced the dimensions of the Thin size to a more compact width of 10.8cm and height of 9cm, while also slimming its thickness down to about half[3][4].
This difference in volume directly relates to the daily behavior of carrying the wallet. The 3.5cm thick Small option generously gathers multiple cards and receipts, making it suitable mainly for carrying inside a bag. On the other hand, the 1.8cm thick Thin option is well suited for carrying lightly without ruining the silhouette of clothing, even when slipped into an outerwear inner pocket or pants pocket.

The internal divider structure of the two options or the weight of the wallets themselves has not yet been confirmed.
