MagSafe wallets and card holders for the phone.
The Benks ArmorGo Magnetic Wallet Stand is a 2-in-1 MagSafe hardcase wallet that holds up to three cards and doubles as a portrait or landscape phone stand. It retails for S$36.90 on Shopee, in 600D, Aurora, and Prestige variants.
The Spigen Valentinus is a MagSafe card holder in two- and three-card sizes and three colours. I bought the three-card version in PU leather for S$21.74 on Prime Day for Li Xiang, a solid alternative to Apple's discontinued leather wallet.
The Spigen Lock Fit is a hard-case MagSafe wallet that holds both cards and cash. I got it for S$34.84 on Amazon.sg; at 62g it is bulky and best suited to a Pro Max iPhone.
The Apple iPhone Leather Wallet with MagSafe retails for S$89, dropping to S$69 during the 12/12 sale. I finally had a use for one after getting the UOB Absolute Cashback Card, which doesn't support Apple Pay.
