Post-it holders?

I believe they are still available. They do come in two sizes - one is VERY small - practically postage-stamp size. I can't remember the price, but they're pricey (duh, they're Hermes!).
 
There was one in curry available at my local H last week so I'm pretty sure they're still being made. I got a PM in January at Heathrow for around $135, and it's actually Box, though most of the others on display (there was a rainbow!) were Chevre.
