I ordered this resin for its flexibility but I found that is not flexible. It is tough but with very low flexibility.

Quite possibly the worst resin I've ever used, so bad that I ended up pouring the remaining 85% of it in to a large vat & curing it all before disposing of responsibly. I was quite excited to give this resin a go & expected good things in the hope it'd be a cheaper replacement for the Phrozen RPG resin i currently use. Lots of vigorous shaking to make sure it was well mixed & in to the vat which raised its temperature to what is recommended. Spent a couple of hours calibrating the resin to my printer (Elegoo Saturn 4 16k Ultra) & then ran a set of prints through it which were duplicates to ones I currently hold in stock (Phrozen RPG). Washed & cured the finished prints which had a glossy finish to them, almost translucent at the thinner parts, the detail was ok but nothing compared to what you get using Phrozen RPG resin. There's hardly any "flex" in the cured resin but probably just about enough to prevent easy snapping points of limbs. When I cleaned out the vat I found thick congealed resin as I poured it back in to the bottle, had almost runny jelly consistency to it along with some very thin cured strips. A very odd experience with this resin throughout , I wont be wasting my valuable time or money with it again. I gave it two stars as it did print to an ok-ish standard but certainly not of a good enough standard to sell via Etsy etc... I've added four images, two are using Tenacious & the other two are printed using Phrozen RPG.
