These planters were chipped upon arrival but I rotated them so the chips and black smudges would not be visible. They aren’t lined and even though the description and FAQ said you can plant directly in them I followed another reviewer who lined them with polyurethane. Even with the extra layer of protection, these continued to crack with indoor use where they’re not exposed to the elements, just periodically lightly watered at the center of the pot. Would not recommend these planter boxes at all, even if you could find a plastic liner to fit the inner dimensions because I don’t think they would hold up, they come chipped due to the unfinished clay construction, and they are smudged with something that doesn’t wash off. Disappointed bc they were the perfect size and aesthetic for what we wanted in that space. May be fine if you resin coat the inside and paint the outside or for use with silk plants but not at all good for real plants, whether indoor or outdoor.
