When filling the eye pillow I decided to rock crystal, because I the alternative flaxseed lavender can not accept due to allergies. The filling conveys seriousness and cool - very pleasant to relax.
The eye pillow is nice and cool, relatively heavy, and makes absolute darkness. However, it slips off immediately as soon as one also turns his head a little to one side, because the fabric is smooth as silk. So I can use the pillow in bed less to fall asleep, as it was rather for relaxing on the mat after the daily training (for health reasons). The available colors are pleasing; I opted for purple.
