What kind of plant is this?

i bought it at a nursery. they said it was a great indoors plant. it is about 9 inches tall (from the bottom of the small pot to the highest part). it starts with one trunk and about 2 inches up, the one trunk splits into three different trunks. which then turn into long bushing skinny leaves. the leaves are about a foot long and they bush out of the top of each of the three trunks. the leaves are about a full centimeter in width, and you can barely see that the leaves are outlined in a red or pink color. the trunk pattern is like triangles. the trunk circumferance is about 3/4 of an inch and each of the three trunks are around .5 inch or less. keep in mind that it is an indoor plant, and i was told it would grow just fine on my desk at work not even close to a window. any ideas?





thanks.
