The 13 cm size sits really flat under jeans, which is exactly what I needed for everyday wear. It's soft enough to feel natural but holds its shape, so no weird shifting when I sit down.

The flexibility of this little guy is exactly what I needed for packing — it bends with my body instead of poking awkwardly when I sit. At 13 cm it's compact enough to stay discreet under jeans, and the realistic shape gives a convincing bulge without being bulky.
Joshua★★★★☆
The flexible design makes it surprisingly comfortable to wear for a few hours, and the 13 cm size sits just right without feeling bulky. Only small gripe is that it takes a bit of adjusting to get the position right under tighter pants.
