Mysore Sandal Soap?

Today I was at an Indian store while waiting to get pizza from the place next door. While I was there I spotted some Mysore Sandal Soap which is apparently the only 100% sandalwood oil soap. A puck of the stuff only cost $2NZD, so I bought it. I'm unsure whether it will work well for shaving (it's big enough to have it's on Wikipedia page, which unfortunately doesn't contain any information on shaving).

I'll let you know how it lathers tomorrow and I'll hopefully be able to use it in the near future.

Also, has anybody else used this soap before?
