The last time Apple produced a folio case for the iPhone was for the iPhone 11. My mom loves folio cases. Sadly, for iPhone 13, Apple stops producing it. So the only way to get a folio case is from a third-party accessories maker like Moshi.
Moshi Overture for iPhone 6 Plus is retailing for S$59.90. There are three colors available, Brushed Titanium to match your gold iPhone, Sahara Beige to match your silver iPhone and Steel Black to match your space grey iPhone.
If you are using iPhone 6, the same choices of colors are available and it is retailing slightly cheaper at S$54.90.
The OtterBox Commuter Wallet For iPhone 5/5s is retailing for S$55 in Singapore. The case adds quite a bit of bulk to your iPhone because it gives your iPhone added protection against drops, bumps and shock. It also includes a slider compartment at the back that house up to 3 credit cards.
On the official website, it states that it can hold up to three cards and one bill, however when I tested it, it is not able to hold even a single note after placing 3 cards in (1x EZ-Link Card, 2x Credit Cards). I guess Singapore currency notes are bigger and thicker because of the materials it is printed on.
Backed the Crabby Wallet on Kickstarter on 9th April 2013, the project got funded on 3rd May 2013 with a total of US$308,838 raised though the initial goal was only US$10,000. I bought 2 Crabby wallets, an orange for myself and a pink for Li Xiang. Paid US$16 + USD $16 + US$5 (shipping) = US$37 (S$46).
They have some mixed up and instead of pink, they shipped a purple to me despite the contents on the delivered envelope stated pink. But Ryan from Crabby Wallet is kind enough to send me a new pink Crabby Wallet and at the same time I get to keep the purple! Thank you Ryan!
