Here’s what his site says:
Each Gum Blonde is 100% chewed bubblegum on a plywood backing. No paint or dye is used. The colour is inherent to the gum – the mixing of colour takes place inside the mouth during chewing using an endless variety of flavours made by an endless variety of companies. Jason Kronenwald has a dedicated team of chewers and prefers the texture of Trident. However, he does not chew gum himself unless he must.”
That’s hilarious! “prefers texture of Trident” and he “has dedicated team of chewers”.
My favorite is Gum Blonde VIII: Britney Spears. yummy.
