Half the size of regular Snatoms, this is the pro version, containing all the atoms of the expansion kit: 12 carbon, 12 oxygen, 26 hydrogen, 4 nitrogen, 2 sulfur, 2 phosphorus, and 4 chlorine atoms, plus 6 double bonds or 4 triple bonds. This kit is not for kids (because the parts are small and a choking hazard).

Please be aware that your item may be held at customs for inspection, delaying the delivery time, and you may be charged a customs fee or import tax or similar. Unfortunately, there is nothing I can do about customs clearance - customs laws make the importer (the buyer - you!) responsible for these fees.
