Shapes and sizes vary. Sizes can range from 10mm to 35mm.
Holes range from 1-4mm. Average hole size is 2mm.
The beads may be a bit dusty due to the chalk lining used when making lampwork beads. Give the beads a wipe and they will shine.
The photo is an example of this mix of beads to show you what types of beads you could expect to receive. They are packed at random so the exact number of beads and shapes and sizes will vary per 100g mix.
It's possible your mix might have more big beads or more little beads. If you have any shape/size requirements please ask.
