A tier of our canned mini-tier collection. The pieces all fit in the collector's boxes with a base area of 4 X 3 cm. A collection of this mineral size, known in English as thumbnail specimens, enables a collection to be built up even in a small space. These small specimens are much more often available in good quality at affordable prices than well-preserved larger and flawless specimens.The steps are fixed either with assembly putty or hot glue. If you want to take the samples, please do not try to remove the hot glue by force. A few drops of benzine on the pad will quickly loosen the connection.
Please note: do not use force to remove hot glue. Put a few drops of white spirit on the floor and the adhesive can be easily removed from the base. The removal of the step from the can is at your own risk.
