Ultra pro generally make good accessories for maps but I think that they are really not complicated life with these pockets ... I precise I've purchased are to protect my deck of Magic the gathering. First thing I **** em: they are too large there can be 1mm on each side too big and 3-4 millimeters up it makes just too much plastic and AC makes them almost impossible to mix cards (dependent on the technique you use) and are very uncomfortable to hold. Then they scratch in a very short time and the cards become VERY slippery (I dropped my deck more than once) when leaving his deck it feels to have to bite the very strong hands for not they fall. The only positive (apart the price which is really low) is that despite the fet that the plastic is very fine it is very resistant tried to break a pockets to test the durability and I just stretched plastic. The cover has not torn. To summarize: In my case these pockets HINDER more than anything else the plastic is really too annoying and AC should not be important, but I think that makes them a little ca cards ugly ... But if you just want to protect maps with which you are not playing at the time the AC could be interesting considering the price is very reasonable, but in general is paid qualitée ca ...
