There are 13.1 and 26.2 stickers... why not a 108 sticker for the yogis who have lived and conquered 108 sun salutations?!
In yoga, the number 108 refers to spiritual completion. It is why japa malas are composed of 108 beads, why pranayama is often completed in cycles of 108, and why sun salutations are often performed in rounds of 108. It is a number of manifestation, renewal and transformation.
**Please note: This sticker is actually clear with white ink. For the purposes of demonstrating the appearance of the sticker it is in black and white here.
