Two class participants proudly showing off their Jelly Boxes from one of the last classes on Sunday of Gencon 2026.
An after-class shot captured from the class area above the hotel lobby of a group of participants who had all taken the class and were excited to show off their Jelly Boxes. We first saw them because the boxes were SO visible from so far away!
Class runner Emily Key helps to guide a participant through making sure that the top and bottom halves of the box are connected together at the hinge point.
Class runner Emily Key brought her blacklight to show just how reactive the green acrylic was when exposed to the light.

Dungeon Jelly Box Kit - Post GENCON Sale 2026

Our Dungeon Jelly Boxes are ready to go home with you! We had a fabulous time debuting these at GENCON at the start of this August, and now we want to keep the crafting going.

Each kit comes with everything you'll need to assemble your box except for one small Philip's head screwdriver. For our classes we use a 1x3 Philip's head from Harbor Freight, but whichever screwdriver fits is perfect.

There are 9 pieces of fluorescent green acrylic, three 3D prints in matte green and 11 small stainless steel machine screws. Con attendees were instructed in class by designer Emmie Mayne, but all that information has been distilled and now comes with instructions to assemble your own from anywhere!

Supplies are currently limited post GENCON. Look for our classes next year for new and fun activities to craft at GENCON 2027! 🟩
