• A low-price indicator has been developed in America to show when a package has been turned upside-down in transit. Called the Tip(N)Tell, it consists of a cardboard "sandwich" measuring 4.5in. by 1.5in. by 0.8in, with a self-adhesive backing.
In between the front and rear layers of cardboard there are two separate spaces divided by a removable wire strip. The lower one is filled with blue plastic beads. When the Tip(N)Tell indicator is fixed to a package the wire strip is removed and if the package is turned upside down, the beads will flow into the upper compartment and stick to its adhesive surface; they will stay in this position even though the package is later placed right side up.
The indicators are being marketed in Britain by A. Latter and Co Ltd, 44 South End, Croydon, CR9 IAN. They come in boxes of 100 complete with "bill of lading" labels. The cost is 4s each when quantities up to 900 are ordered and 3s '7d each for lots of 1,000 or more.
