I bet 5 stars for efficiency. Because the fireflies came pretty quickly. In this regard, the seller is well done. But misled. 20 and 50 is the number of fireflies. One by one. ie 10 packs. 50 pieces. For some reason i thought that there would be 20/50 packs of 5. the price turned out as well as the bought from us in the city. The point was to order. Therefore дороговато. Misled sold. Try return of the cost. Because. On the cover отчётливо seen what in package lays 50 packs. Accordingly, why lies only 10... unclear.
