Easy way to try a few medium hides of different shapes, and for reducing enclosure weight by replacing a few real rocks. For size reference, if used as hides, they will work for adult leopard geckos or hognoses. Too small for my 4’ corn snake (not that it would stop him). Definitely handsome enough to just be used as decor if hides are outgrown. Easy to cut an entryway with tin snips, and scrub clean with a toothbrush.
