Retro 51 Desk Sets - Red Classic. This classic set is a staple for any desk. The metal formed base is weighted so it will not slide, plus it is covered with a velveteen bottom to keep the desk top safe from scratching. A matching rollerball pen sits in the base and waits for your instructions. Whether for the office, home or use at a wedding, you’ll find these sets to be functional and eye-catching. It comes with a rollerball refill, but it can be converted to a ballpoint (sold separately).
