DiscoBasics - Extendable 3D Shrimp Net
Discobee loves and uses these nets exclusively.
These are by far the best dwarf shrimp extendable nets you can buy. They extend from 6 inches to 24 inches.
These nets hold their shape, the net opening is ~2 inches. The handle is coated for better grip and there is a ring so you can hang it if desired.
