Had some Diamond strike anywhere matches in a screw top aluminum container for fifteen years. They did light but not as if new. If I were going to put up strike anywhere matches, a good idea would be to vacume seal them. If you don't have a vacume sealer, go to your local sausage maker. They would probably do it for about .20 cents per box. Your Coghlan waterproof matches at $3.95 per 10 boxes would also be a good choice for long term. They are not strike anywhere, but they make a flame. Another plus of vacume sealing would be no oxygen for fuel if ignited accidently.<br><br>Regards<br>Hunter
