Review on High-Quality Red TPU 3D Printing Filament With Dimensional Accuracy For Professional Results by Aaron Ayo

This is flexible, but not very soft and certainly not easily flexible. I intended to make stress-balls as my first print with it, but while the material printed quite smooth and easy with a brass 0.4 nozzle, the end result resisted squishing more than expected with only 3 layers of wall and 10% infill. Don't let that discourage you, though, I will still happily use this to print spacers, bendable toys, flexible connection pieces, RC car wheels, and MUCH more! Just.not stress-balls!
