Kamae are great Siwan..good quality andc reasonable. It was a Kamae one i lent to you on Monday.
But...about getting your name in Kanji - you can't Kanji is a pictorial alphabet and kanji is essentially picture words. To get the sound See Wan Err Enn eed you need to use Katakana.
I don't like the use of Katakana I would be Gu u inu Mo ru Ro which is silly.
What I did with the belt you borrowed on Monday was ask them to put the Seki Ryu Zan Kanji on both ends. This is the pictorial alphabet for Red Dragon Mountain which makes more sense.
