More products such as mugs, shirts, stickers, and tote bags: Redbubble
Art prints (shipped from USA): InPrnt
Those two are print-on-demand shops, meaning they are made to order by Redbubble/InPrnt. This allows me to offer a wider variety of products without running out of storage space at home!
All of the prints and bookmarks here are also available on Etsy. Those orders are all fulfilled by me, just like the orders in this shop.
