When you go to shop all brands, and go to X-Z, not all the brands show. After scrolling further than YoyoJoker the box disapears.
Scroll your page up a bit before pulling down the “brands” drop down menu. Scroll it so that “brands” is on the top line of your browser. In fact, on firefox you can scroll the page much higher but the top menu stays visible.
This is on a computer, phones may work oddly different.
I think if you click on the “BRANDS” [https://shop.yoyoexpert.com/collections/brands] button, or click on the “Shop All Brands” [https://shop.yoyoexpert.com/collections/brands] button, it should bring you to a page with every brand on it. This does lead to a lot of scrolling though, so it may not be the best option.
My computer does the same thing though, not showing all of the brands that there should be in the column. The farthest I can get to is YoyoJam.
