The retail price of a 3M N9501V before the Cov-2 was about 4 Yuan, in mainland China, for a box of 100, plus postage (I used to buy for staff and leave on the front desk for high pollution days) which accounting for CNYUSD at the time was about $70. $40 for 10 sounds high. The current price is an order of magnitude higher (consistent with article material sourcing prices). Pricing seems very demand-elastic, and not only masks, the Just-In-Time supply-chain, regardless of China or anywhere, seems very vulnerable to low-probability (but inevitable, don't like to use the term 'black swan' as it's not, something big happens every decade) large impact events.
