After opening, I used it once and then left it unsealed, and it hardened completely. Another bag is in the same condition, and I am currently using it in a paste form by adding water. Since it has hardened completely, you will need to add water or lukewarm water directly into the bag to make it into a paste before use. Please purchase only if you understand and agree to this. Packaging will be quite simple. Price negotiations are not accepted. Please refrain from purchasing if you are sensitive to this. This is a bath additive made with Dead Sea salt, and relaxation effects can be expected. - Product Name: Dead Sea Salt - Brand: NICHIGA - Features: Dead Sea salt - Usage: Bath additive/bath salt
