I have seen them at our local store.
They are a brick & mortar store we go to, but they also have a online version
My wife and kids go here.
But they also buy online from here:
They mostly use this brand
For me, I do the washing! Nothing ruins brushes and furniture like dried acrylics!! :)
Yeah, the Royal Talens Amsterdam ones are quite popular here. I am not sure how different they are from other brands as I am not that experienced with acrylics yet. But I have seen the other brand you linked as well so maybe I will get them to compare :)
