Perfect size. Kids need room to play and a cramped little turtle box is too small. I ordered organic insect repellents, neon green and purple sand to mix and my “world’s most efficient competent son-in-law” planned to line it with weep holes and fill with sand. I included organic mosquito repellent to mix with sand. Highly recommended. Texas A  M or Okla State can tell u safe organic pest control to use. Highly recommended!
