I'm pretty sure there isn't a direct way to do it. But when you go on a product page, under Manufacturer, there is a little "i" next to the name of the company. If you cover over that, it has the option to go to "All [Company] Products". Click that and it'll take you a search for the company, which seems to be what you're doing, anyway. It says that XHale Glass (or Xhale Enterpries) only has 17 products which you can find here.

Another way to see the products is to go to the company's EdenLink page, if they have one. Here is XHale Glass's page. If you scroll down, it has a list of their products that you can check out. It lists it as having four "Butt plugs", eight "Glass", and eight "Glass, steel, ceramic" but the latter two are the exact same. So here, it says they only have 12 products. It's weird. I don't know. They should add an actual way to search by companies but for now, those are basically your only options. Good luck!
