The main collection comes in three different sized boxes with one being a window box. The large boxes (issues 1-6 and 12-29) measure 277 x 197 x 155 mm, medium with a window (issues 7-11) are 227 x 197 x 155 mm, and the smaller ones (issues 30-50) are 233 x 184 x 102 mm.
According to my own collection issues 7-11, with the window boxes, appear to be marked on the bases with the lowest serial numbers, ranging from AAB-nnnn to AAD-nnnn. This suggests that these were produced first but released later in the series after a reshuffle of the order.
Each figure is packed with a folded leaflet measuring 210 x 170 mm with limited information relating to the figure in four languages, English, French, German and Spanish. All sizes given include the bases.
