I make cold brew coffee in mason jars on the counter. My wife wanted them to have a home.
I used Home Depot whiteboard, it engraves nicely and doesn’t need any masking. We will have to see if it gets too wet after time.
This is after I have removed the coffee grounds infusers. (These will go into the fridge and a new set of jars will go in.)
Here is a test project I did in Cuttle to get the settings dialed in.
You might want to try some white acrylic
I can get the whiteboard for < $20 for a 4ft x 8ft 1/8in sheet, vs a 12in x 20in sheet of acrylic. If it become an issue I can try sealing it.

That turned out really nice! When i first read you response “If it become an issue I can try sealing it.” I thought you wrote “If it…I can try stealing it” 
I really like the attached sign. Nice!
Coffee and Glowforging two of my favorite things!
Nice use if that white board. I haven’t use it yet, but I’ve heard good things from the crafting world.
Nice idea. Over time acrylic would be more durable depending on how much it’s used
