Veracity filament from Filastruder that is manufactured by Keene Village Plastics and comes with access to average diameter stats on every roll. As of 12/21/18, $25 per kg for masterpool refill. All rolls came vacuum packed with desiccant and came with large zip ties for storage and an extra sticker to put on the spool to identify the material.
All 4 rolls I’ve inspected were typically 1.74 or 1.75 average which matched the online data for the roll. Looking up the data online was a pain that required you to create an account with KVP and then enter in several different codes, some off a piece of paper in the box and some off the sticker for each spool. No impurities were seen. Masterspool refills would sometimes feed awkwardly off the roll, but not to the point where it caused issues.
