I created these potion bottles, I cast the bottles themselves out of resin. The one stopper I molded out of clay and created a custom mold. Once I had those done, I added some proper D4s and there you have it.
The decision to cast my own bottles out of acrylic came about as I wanted something for my players playing in the sessions I am going to run at the Long Island Table Top Expo in April and the glass bottles I tried broke when shaking them with the dice. This is just a little too worrisome. I’ve dropped one of these on a concrete floor and besides a small imperfection, the bottle is fine.
I have one that I wrapped some twine under the lip of the bottle, I plan to make a few like that and some plain.
I may also partially put some resin in a few of the more clear ones to make it look like a fluid is inside the bottle.
