Inside the wider sections of my leather wallet, a sleeved card still fits. I moved rarely used cards there and kept one daily card in quick reach.

Tear-resistant construction feels firmer than a paper envelope, yet my bank card moves in and out without catching at the opening.

My partner and I each used one RFID sleeve and kept the third with a backup card. The slim protectors added little thickness to our travel wallets.

Before an autumn city trip, payment and travel cards went into the aluminium-lined sleeves. Each card remained easy to identify by its top edge.

Without batteries or an app, the pack provides a straightforward physical barrier. I labelled the three sleeves so family cards did not get mixed up.
