Review on SOMGEM Cigarette Case With Lighter: Airtight Joint Holder, Smell Proof & Waterproof For 20Pcs 84Mm Cigarettes & Prerolls - Multipurpose Pocket Box Container For Outdoor. by Maurice Rivera

the case lacks an o-ring so it probably isn't water tight, but it is secure and short of dunking appears basically waterproof. In mine the lighter lit 5 cigs, before needing a charge, once it got that 1st charging has worked even better. The Lighter takes some effort as accuracy is needed to hit the spot while holding the lever to activate it. if I didn't wear glasses it might be easier. The optional lanyard is also more robust than it appears, i thought the really thin part would give way, but it has held up beautifully.The case is for regular filtered cigs, it looks as if it may hold 100's if the lighter were removed, but even then the hinge and cap would crush some opening and closing the box, I was going to test the theory if the lighter had died, but got a good one, so thats just a guess
