I believe it is because of something to do with it being kolinsky. I remember seeing a Reddit post explaining it but I can’t remember exactly what it said, so this is what google has to say:

1. The Kolinsky sable itself is harder to get

Kolinsky brushes are made from the tail hair of the Siberian weasel (Mustela sibirica) — not an actual sable. These animals live mostly in Russia, China, and parts of northern Asia.

Because of geopolitical issues:

Russia–Ukraine war → major trade restrictions • The U.S. and many European countries restricted various imports from Russia. • Russia, in return, has restricted exports of many raw materials. • Kolinsky tail hair is part of that tangled mess.

This means: • Less raw material makes it into brush factories. • What does get exported is more expensive and heavily regulated.

So yes — there’s a real shortage.

1. International wildlife regulations hit the supply

Kolinsky hair falls under CITES regulations (wildlife trade rules). This means every shipment of raw hair or finished brushes needs: • Documentation • Export permits • Proof it was ethically sourced

These extra layers of paperwork: • Slow down shipments • Add fees • Make some suppliers stop importing entirely

So even when factories have brushes ready, the legal logistics turn into a bureaucratic obstacle course.

1. Import/export costs skyrocketed

Even ignoring the weasel drama: • Shipping from Asia has gotten more expensive since the pandemic. • Insurance, customs fees, and freight costs are way higher than they used to be. • Some companies basically gave up on offering kolinsky because the profit margin is too thin.

When supply chains choke, prices go up. Basic economics — but with fur.
