Uni-ball Signo Sparkling UM-120SP Gel Ink Rollerball Pen 1.0mm Green Box of 12

uni-ball publishes the Signo Sparkling ink as waterproof pigment ink, and that is uni-ball's own wording against UM-120SP. It is not described as permanent, and uni-ball publishes no test standard behind the word, so treat it as water resistance rather than a guarantee.

uni-ball does not publish that for UM-120SP, so we are not going to state it either way. The product images on uni-ball's own page are the best guide until we can confirm it from the pack.

Eight: gold, silver, blue, red, orange, green, violet and pink. Those eight are the ink colours named on uni-ball's safety data sheet for UM-120SP.

Yes. uni-ball publishes the UM-120SP ink as acid free, which is the specification that matters for scrapbooks, albums and anything meant to be kept.

uni-ball's safety data sheet classifies the ink as a skin sensitiser, Category 1, with the signal word Warning - it may cause an allergic skin reaction. Ordinary writing is not the concern; avoid prolonged contact with the ink itself.

uni-ball does not publish a refill code for UM-120SP. The plain UM-120 takes a UMR-5N, but we are not going to assume the Sparkling version is the same one.

Twelve pens, all green. If you want the eight colours together, the assorted wallet of 8 is a separate item.
