When backpacking, I just "add boiling water". But when we tailgate camp, grandma brings the entire kitchen. I'm only smart enough to use half a dozen spices, mainly salt, pepper, garlic, onion, mustard and ketchup, :tinysmile_twink_t2: but grandma and my daughers use all kinds of stuff that I can't even pronounce.:tinysmile_fatgrin_tHow the heck many spices are you taking along that makes this idea necessary? I only take salt, pepper, garlic and onion powder. It is a cute idea and all, but I wouldn't need them.
I have seen the same idea but for Neosporin and Vaseline for first aid kits. It's single use but they work well for day hikes. We don't use tape though, we just take a lighter and seal the ends.Great idea!
The one I've used (aside from a little multi-compartment spice box I bought at Cabelas) is to use large drinking straws, cut them to the length you want, fold one end over and tape it, add spice and fold the other end over and tape it. You can write the name of the spice on it with a marker.
They're basically single -use and don't hold a lot, but they are cheap and handy.
