These standard size jar lids I work with will fit on both the 4oz size as well as a taller 8oz size, so you can choose which you'd like.
These originally 2-part lids are fused together once the glossy resin is poured into the top, so it twists on and off of the glass jar as one piece.
The base on this jar is done with a color-shifting blue/teal shimmery paint. The text "this is what space smells like" is done in glow-in-the-dark vinyl that looks white in the light, glows green in the dark. The lid is then filled in with glossy clear resin with a brilliant shine.
