These dotes are durable! They are perfect for farmer's markets or any time that you need to carry a lot of stuff. I hope you can tell by the pictures but they can be snapped in on the sides. The snap-in tote is 13 inches across the bottom and 17 inches across at the top. It is 16 inches tall and 5.5 inches wide. When snapped in the measurements stay the same except the top is 10 inches. The tote is super strong and it holds a ton.
