A liquid may interact differently with components such as seals, coatings or applicators. Leakage, discolouration and changes over time are practical considerations.

Compatibility is assessed using the actual product, not by appearance alone. A concept image cannot confirm whether a package is ready for sale.

Look for accurate product presentation and follow the care instructions. Finished specifications should be confirmed separately from creative designs.

An attractive format has to work in ordinary life. Check the finished product's directions, capacity, closure and available specifications before choosing it. XASIS currently presents its Signature Five as fragrance design concepts in development; final notes, formula details and availability are confirmed only for finished products.
