This jar is roughly 5x2inches and can hold up to a half. It is smell proof, moisture resistant, and has a child lock. Press down and twist to open. The image is protected from scratches with an epoxy top layer. The jar itself is water proof and leak resistant but if you submerge the lid in water and it gets under the image, it may ruin your image with water damage, but will not ruin the contents of the jar. Everything inside the jar will be safe! Fits perfectly in a purse or pocket.
