It's not a secret, I make my own stickers, I sell them through Gumroad.
You can buy them right from this page. Ok, so here's what you can do:

Pick different sizes

I can print individual stickers reliably fitting an A7 sheet (7.4 x 10.5 cm = 2.9 x 4.1 in) or an A6 sheet (10.5 x 14.8 cm = 4.1 x 5.8 in).
You can pick them from these bundles:

Buy pre-combined sheets

Make your own sheet

Here's a super awesome thing which I've built for you people. It's a STICKER PICKER.

You can pick ANY stickers from ANY theme below. There are more than 50 :-0

Tap any 6 stickers, click the "I want these!" button, it'll give you a code. And then you go to Gumroad and at checkout paste that code in a form.
You can buy multiple sheets at once, but don't forget to generate multiple codes and set quantity at Gumroad to how many sheets you want.
