Two-wheel casters are attached to the bottom, and the case can be pulled and carried by the side handle grip on the top. In addition, protection is placed on all inner surfaces of the case, and a tripod fixing strap is also included. Therefore, it excels in shock absorption during transportation. This is a multi-tripod case with robust construction that allows it to be checked as baggage on flights. Internal Dimensions: 107mm x 220mm x 220mm External Dimensions: 1160mm x 290mm x 260mm Purchased new about a year ago. Used it several times. There are dents in several places on the inside bottom (due to a large tripod being placed inside). Zippers and casters are in good working order. Overall, there is little dirt, and the condition is good.
