A custom industrial shelf made of pipe and concrete. Takes about five days to complete (three of that is concrete curing time), but we have incredibly detailed step-by-step directions if you want to tackle something similar.
5-Hour Energy type bottles are perfect for transporting liquids, powders, and herbs and spices. They hold 1.93 ounces, so they’re small enough for carry-on luggage. They are very sturdy, so they ship remarkably well. I have used these to send powders and tinctures to friends, as well as to collect water from various locations. Easy to use, easy to carry, and easy to store. These are not permanent storage bottles, of course; but if you just need something solid for a limited amount of time, these little things are a godsend :)
