Flexible Foam Curling Rods

Is a pack of bendy hair rollers, also known as flexi bend rods or foam hair curlers. 
These hair styling tools offer a no-heat solution for creating curls and waves. 

Material: They are typically made of soft, flexible foam or pearl cotton that can be bent, twisted, and rolled without the need for clips or pins. 

Purpose: They are used to create bouncy curls or waves without causing heat damage to the hair. 

Usage: They can be used on either wet or dry hair and are often comfortable enough to wear while sleeping for overnight curling. 

Packaging: A pack usually contains multiple rods, often 10 pieces, in various sizes to achieve different curl types. The white circle with "20" likely indicates a diameter of 20mm.
