As others say, the envelope contains twice as long strings so you cut them in half and you have two sets of strings, so the price is aligned with other products. Every string comes in separate plastic envelope with a progressive number and relative note clearly written on, you can't go wrong while mounting. Strings material seems pretty resistant and mounting is fast and easy. Two major issues: first, strings are smooth so when you play with your finger pads, some of them tend to be squeaky (mainly the first string). You can solve this with a couple of passages of very thin steel wool on the string where your finger touches the string. Second issue is intonation: for the first 2-3 days the strings sound out of tune, you have to tune a thousand time but the intonation is not stable. After some days the strings settle and they sound with the correct pitch. I have had this problem mainly with 4th string (the low D string). The only thing you have to do is knowing this and be patient some days to stratch the strings with constant tuning. The sound has a brilliant component but mainly it has a thick body, with sweet nuances. Sound volume is good, sustain could be better. I have been in mail contact with the producer and he assures me the difference with clear Worth strings is brown ones are made of a different density PVDF. So material and gauges are identical, the sound is different because of different density of brown PVDF confronted to transparent PVDF. I play these strings with fingerpicking tecnique on a Thomann lute baritone ukulele and they sound great, the overall result is intimistic and very close to a real lute effect, perfect to play renaissance and baroque music (you can buy a lot of book on Amazon compiled by Michael P. Walker where you find a lot of this type of music transcribed for baritone uke, they are very pleasant to play). My overall assestment on these strings is very good and they seem to last for a long time with many hours of nice sound.
