[BOUGHT] WTB Cheap 2x HTD 5m 8mm Bore 16-20t Pulleys

Where can I find 2 of these pulleys between 16 and 20t? I accidentally ordered them with a 10mm bore from China, and I don’t want to order it from China again due to the long shipping.

They’re out of stock! But it’s ok, I found some on builtkitboards! That should come soon, hopefully
