Stable Box

4 packs, each containing 4 vacuum cleaner bags in a sturdy plastic box, plus the extended warranty, the yes at such an expensive vacuum cleaners can not hurt. Too bad that even "reputable" manufacturers only give "legal" small-time 2-year warranty at no extra charge. Anyway, the 4 packets are stored in a robust plastic box that resembles a very large Tupperware box. Very handy, because you have the same a certain stock of bags and know where to have the documents for the vacuum cleaner: The box has namely space for the documents to the vacuum cleaner, ie invoice, printed warranty, operating manual etc.
Good idea well implemented. The price I consider as an additional cost for the 5-year warranty, the vacuum cleaner bag you get comfortable in of inferior quality also cheaper.
