about the owner

hi, I'm arielle milstein-brennan!


I created CriticalKits (now Fantastic Knickknackery) in 2015 as an Etsy shop and had my 15 minutes of fame by making the first ever dice jail that Laura Bailey used on the wildly popular Dungeons & Dragons show Critical Role. 

Since then, I’ve created tons of fun & helpful accessories for on and off the TTRPG gaming table, including three successful enamel pin Kickstarters! Tokens, keychains, pins, pouches, magnets, lanyards ... w
hatever your interests, you’ll find something here you like! Plus, I love taking custom orders! Check out the FAQs for more information.


Do you like supporting artists of marginalized identities?

Sweet! I'm an AuDHD Jewish woman on the ace spectrum!

I've been creating things forever: 

  • friendship bracelets at 7

  • gravity-powered cardboard micro machine racetracks at 9

  • projects on my mom's sewing machine at 11

  • tiny clay sculptures & increasingly complex plastic lace keychains in high school

  • vector graphics and stop-motion animations in college

  • and as an adult ... laser engraving, machine embroidery, vinyl decals, macrame, jewelry, over-ambitious cosplays, & anything else I can get my ADHD hands on

I have a bachelor's degree in photography & digital media with a minor in graphic design, and I'm also certified to teach K-5 and middle school math. And if that's not enough, I've also been:

  • a college tutor, tour guide, & orientation advisor

  • a craft store cashier

  • a substitute teacher

  • a children's bookseller & storytime princess

  • a barista

  • a farmers market booth runner

  • a catering server

  • a children's science museum educator

  • a birthday party operative

  • an after-school program instructor

  • a substitute teacher again

  • an admin & teacher for a tutoring center

  • a small business owner
