Round black beaded coaster 10 cm

Key measurements for finding the right spot:

• Diameter: 10 cm
• Thickness: 1 cm
• Weight: 0.04 kg

All you need to know about materials:

• A single strand of black glass beads wrapped in a spiral
• Eight clear stitches sewing the turns together, left visible
• Slightly lustrous opaque glass
• Raises the glass by half a centimeter, does not retain water
• Diameter 10 cm, 0.04 kg
• Sold individually, indoor use

Ten centimeters is the size of a saucer: this disk disappears under the glass instead of surrounding it, and all you see is the black rim sticking out. This is exactly what you want from a coaster on an already crowded table, where a larger set would be redundant.

What you need to know for installation and maintenance:

• Never run the piece under the tap; wet thread loosens as it dries.
• Do not pull on a protruding bead; the spiral would fan out.
• Dust with a dry brush between the turns.
• Wipe the table after a cold drink; condensation seeps between the beads.
