To prepare for our trip to South Korea, Kat and I dropped by at Handyman to look for an Adapter suitable for the country's outlets, Type C plugs.
Type C Plug and Socket
I was meaning to get a simple plug adaptor but the Handyman staff showed me a universal travel adaptor with 3 plug types.
It is suitable for future travels. Too many plugs would just be a mess at the house and eventually be misplaced. But this plugs could be reassembled to make it compact for travelling.
