Frinkles are tiny blobs of glass, often given a colour wash (in all different colours) that are used in various types of craft applications.
They can be glued onto a piece of jewellery as an infill, or onto any other craft surface (cardboard, wood, plastic, etc) to give a shimmery, almost frosted look.
They come in different sizes,
the biggest being about as big as a very small seed bead, and
the smallest like tiny seeds.
They can
generally be found in craft shops, but can be hard to source sometimes.
