Why Rev 4? Here's the backstory:
We've been fighting production problems with the current design of the film holders (rev 3). The “thinness” of the plastic causes some of them to warp when ejected from the mold. While they were better than Rev 2, we were still having to discard way too many parts!
Taking one of the lessons learned while testing the SP-8x10+ tray system, we've added texture to the face of the holders (see photos). The texture breaks the surface tension and keeps the film from sticking while letting us to increase the base thickness, eliminating our warping problem.
It will be shipped via USPS Priority Mail Padded Envelope with insurance. Typically takes 3-5 business days & includes tracking. Local shipments have been taking 1 business day!
