The LEGO x IKEA BYGGLEK Collection is now available for purchase online. This is a collaborative project between the companies which was announced back in 2018. The only thing is that you might run into an issue shipping the items and can do an in-store pickup. A majority of the stores here in the US also has the products in stock if you want to go there and shop.
