This is Crazy Aaron’s Mix Your Own Mac & Cheese Thinking Putty — a tin that includes everything needed to build the final putty: clear Thinking Putty, a yellow “cheesy” color-izer, and a rubbery noodle mix-in.
Mix the color-izer into the clear putty, fold in the noodles, then stretch, snap, bounce, and sculpt the finished putty. Rated fun for ages 3+; the finished putty never dries out, so it stays playable between sessions.
Crazy Aaron’s Thinking Putty is manufactured in the USA from non-toxic silicone. Per the Amazon listing, the product is produced with the assistance of exceptional individuals challenged with disabilities — a long-running part of Crazy Aaron’s commitment to inclusive manufacturing.
