I wish I had the knowhow to invent something. I've had ideas, but nothing to the point I could profit from. Have you ever invented something that actually did good in making you money?
I'm not sure if I'm the "true inventor" of this, but I can honestly say I've never seen it around. Not before I started creating them, or after.
I was making these air fresheners using beach sand.
I would take trips to Florida and Myrtle Beach and always bring some sand home, plus any little beach decorations or trinkets I would find in the surf shops.
Then once I got home, I had these little round plastic containers (bulk/dollar store) with see-thru lids to keep them fresh.
I'd fill each one with sand, mix in coconut and vanilla candle oils, let it dry, then put a small beach decoration on top of each one, sitting in the sand.
I got 2 party store owners to sell them for me, one tobacco shop, and my dad's hardware store.
(These sell best during the winter months because everyone's bored. Also, Christmas (gifts).
