tip installation
I find if you moisten layered tips a bit on the very end before you blade them, they cut much smoother and even. personally i lick my finger and just touch it to the end of the tip...drives the chicks nuts at my booth too lol
Wizard tips
I use the Wizard tips as a Moori replacement and I am happy with them also. I've had a couple customers complain about Moori's not taking chalk like they used to. I used a tip pik and it took chalk a little better but I find them not like they used to be either.
