In the set cheaper! Some products work best in combination. The best example of this is the static grass from ZITERDES. In order for the standing grass to work really well, you need the grass-glue and the grass applicator in addition to the static grass, in which you can electrostatically charge the static grass. To make it easier for you to search in the shop, we have created sets in which we have already put together the matching articles for you. On top of that we put a little discount on it! Thus, the sets are not only useful, but on top of that also inexpensive.
