I prepping a tour to head to Germany and they are asking I send Gel for some units I've never heard of or never heard referred to as these. Any guidance would be appreciated so that I can get the gel cut and start to know what they are talking about. (I did Google all these nomenclatures and failed to find anything useful)
HPS 23 and 30
1K Assymetric
HPZ 15/40
