Hello. I am sending an item through the mail to get signed by an actor. I messaged his son on Facebook and he already agreed to sign. I want him to use a paint pen on the clear panel of a Funko Box, but I am worried that the ink might bleed, smear, or otherwise not turn out correctly if the paint pen is not used correctly.
Any suggestions on instructions I should leave the actor on how to use the pen correctly that won’t be overly complicated? I am thinking something along the lines of "1. Shake well", "2. Test pen on paper first" and "3. Let dry for 20 minutes after signing".
Thank you!
