Good Quality Drawer Pulls

It's going to depend on the style that you're looking for... colonial, modern etc.
I have bought drawer pulls at the Hardware store on the carretera immediately to the west of Intercam (Intercam and Oxxo plaza). They also have the screws of various lengths but not necessarily stainless steel.
However, I was looking for a specific kind of pulls for my kitchen drawers and found them on Amazon.com... they came with screws. If the screws are too long, you can use extra washers on the inside. If they're too short, counter sink them from the inside.
If you put in the Mexican address that you want to deliver them to, they will tell you IF they ship to Mexico.
I have things from Amazon.com shipped to iShop all the time and I don't have a box there... around 30 pesos a package but it depends on size.

With the iShop address, nearly every single knob "ships to Mexico" appears in the choice. You can whittle down the choices by the style and colour on the left sidebar.
Have fun!

Here's what's available on Amazon Mexico... https://www.amazon.com.mx/s?k=drawer+pulls&page=7&crid=MCUUTZ2RN4SC&qid=1634304517&ref=sr_pg_6

Both Amazon sites have 7 pages of choices but the Amazon Mexico site has very different choices.

I hear ya. I'm a fussy arse and like quality but also love a good price. It's been four years now and I've had no problem with any of the knobs I bought from either the hardware store or Amazon. Still look the same as the day I installed them.
