i bought 3 packs of these strings 
the La Bella Nylon Junior Set FG114 -14, also the 1/2 size and i used untill now 2 packs, my experiance with them untill now isnt good at all 
 
- both packs seemed to be old, or already corrosioned, because the strings made my fingers black 
i play various string instruments and never ever had this only with this brand 
 
- they also dont hold very long, but at least the weak g-string is double in the pack 
 
+ sound is ok 
 
- price is quite high, specialy for this quality 
 
for my half size guitar i will get noprmal size but high tension 
for the 1/4 size guitar i will have to see what else i can use 
 
maybe i had 2 bad packs but i guess i dont buy them again
