I use a fair number a match's. Round home I keep the strike on box ones round cause the strike anywhere's er harder ta find. Well the youngest boy smokes, so he keeps takin my box a match's out on the deck ta his smoke. Well, he still ain't learned ta bring the box back in! Twice now he's left em out there an they've got rained on, I mean soakin wet! This last time the box actually started comin apart, had ta tape it back tagether. Well, figurine I didn't have nothin ta loose, I let em dry out good an the darn things still work! I see no difference in the performance of a box that never been wet before! Now I don't recommened doin this on purpose, but if yer match's ever get all wet, try dryin em out good before ya toss em!
