Can you guarantee high purity? Has it been in contact with metal, glass or skin?
For anyone looking at this deal - this is a pretty damn good price for 30g. Gallium usually goes for $3.50 per gram so here you save $40 and shipping. The stuff is awesome. You might want to read up on how to make FS mirrors with it too!
I have some too, its pretty neat stuff, melts in your hand . I "Cleaned" mine when it got dirty by "spinning" it around a small glass tumbler in warm water, all the impurities seperated from the gallium. Had to do it about 10 times though to get it clean. Nice price for a very nice product - good luck with the sale PR.
