Multiple Outlets in One Plug
Style: Type C Most of Europe - 3 Pack
Highly recommend these. Multiple outlets in one plug with quick charging and flexibility. Great having three of them as my husband used one, while I had another. No issues with compatibility in Paris and easy to input

Work well!
Style: Type C Most of Europe - 3 Pack
Love these! Used them all over Italy and Switzerland a bit too. Hair styling tools worked great, they never fell out of outlet. Did not overheat. Easy to pack.

Quality and security-oriented wallet
Color: Adventure Brown - Forest Brown
This is a neatly constructed wallet. The material of the leather feels satisfying to carry unlike previous wallets. This wallet consists of many card slots, and allows ease of access between them. The wallet can fit checks, cash and is just a nice layout and style to be able to look through it. Because some of our cards support RFID and NFC technology, bad actors can try to steal our credentials. This wallet has a material to mitigate these occurrences, but like anything in security whether it be physical security controls or the wide scope of cybersecurity, do not rely on it and try to be up-to-date with the trend. I am sure we would all want to be one step above in relation to keeping our credentials secure. Still, it is an excellently built wallet and I highly recommend it.

Cards load easier and easy to remove them to use. Holds money and cards for easy use. Nice and supple and wears excellently. Good quality leather and card slot are bigger then other wallets I have tried.

Beautiful Wallet
Color: With NO Logo - Smooth Nappa Black
Well constructed and beautiful wallet. The black Nappa leather I ordered is soft and smooth to the touch and you can tell by the look, feel, and smell that it is high quality. I love that you can order this with both a logo and no logo for a clean look.
The design on this is well thought out.
I'd definitely recommend this wallet to anyone. It is an amazing value and far superior to any other $30 wallet I've ever seen.
