Transition "Mystery" Color Filaments Now Available for Purchase!

Some of our local Coex fans are familiar with our transition “mystery” color filaments. NOW, all of our fans on the web can get their hands on these “mystery” color filaments, too!

Our transition color filament is the same high quality filament that Coex customers trust… but in “mystery” colors. The unpredictable colors are the result of our changeovers from one of our standard colors to another during production of our filament and cannot be reproduced. We can never guarantee or offer a specific choice of colors to our online customers as there’s an ever-changing rainbow of colors available here at our facility on any given day. Simply let us choose a color for you and — here’s the best part — you will receive 1kg of our filament for the 500g price!

These “mystery” colors are available in 1.75mm PLA, PETG, and ABS while supplies last. But check back often if a particular filament type you’d like in a transition color is currently out of stock. Stock status of these “mystery” color filaments changes from day to day!

Call or email us with any questions you may have in this regard – (920) 757-1055 or

*Please note that these items are not returnable or refundable due to color and we will not guarantee or pick any particular color for you. Remember – the color is always a mystery!*
