Unity Candles?

For those of you who bought your unity candles, first where did you buy them and secondly were they engraved/embossed/written on etc. on the actual candle or were your candles just wrapped in for example vellum or paper of some sort with your initials or whatever you wanted on them?

Thanks for the info!

I don't know if I want to do them myself or if it is worth getting professionally done.
