T3000 / T3500 cases


I bought these to mount behind the saddlebags on a motorcycle. They are used as tool boxes. Good, solid plastic boxes that are strong enough to hold up mounted on their sides. Thin but firm foam inside to quiet down any rattling. Waterproof seals held by nice solid latches. Great price and fast delivery. A positive experience for my first order with SunnySports.




from Castle Rock, CO, US

This box leaks on any dive over 30 feet deep. Checked to make sure nothing in the way. Still leaks.
