Start with the technical question
Compare Nylon and PET constructions, check thickness units, distinguish flat from inflated dimensions, and choose the correct inflation method for the size. Read floating-time guidance together with its indoor conditions and appearance stages.
Interpret performance claims accurately
The numerical examples in the core guides use the confirmed UNDALO multicolor number-balloon specifications. They are not blanket specifications for other products. Use the agreed product specification for requirements not covered by these guides.
