The lash jewel is made of two parts. A long magnetic stick and the part with the jewel.
1. First put the stick onto your lashes.
2. Now take the jewel part and put it under your lashes.
3. The stick and the jewel part will move together because they are magnetic. Your lashes are between the stick and the jewel part.
Move the jewel carefully in the position you like.
The lash jewel will hold much better when it is nearly close to your eye lid, not on the lashes end.
