Bottles, jars, and tubes
Capacity, material, wall thickness, cap fit, tube sealing, pump or dropper function, stock mold availability, and decoration method should be clear before comparison. Treat bottles, jars, and tubes as part of the controlled product specification. Record materials, dimensions, tolerances, variants, finish, labels, packaging, approved sample, and allowed substitutions, then route any change through written approval before production or a repeat order.
