This is a Legend Of Zelda Lon Lon Milk phone charm. :)
The 'milk' substance is made of resin, so it is solid.
Choose it on either a dust plug or cell phone strap.
The little bottle with cork stopper is 13 x 18mm. The cork is glued in well and the label is sealed so its water resistant.
THIS PRODUCT IS HANDMADE IN THE USA AND IS NOT AVAILABLE IN STORES. GREAT SELLER!!
Although it is sturdy, the bottle is glass, so try not to be too rough with it.
Also it is not waterproof, as cork will become soft and crumbly if it gets wet for too long. (Although it is water resistant, so a little water won't hurt it. But don't soak in water or take it in the bath or shower.)
PLEASE NOTE : Due to the high demand of certain products, some may take longer than others to arrive.
