Monster Erasers - What reward?

I am pretty close to completing my collection, I just need the Lupin Eraser!
With the erasers, I can either get a Glowing Whip, or a Blue/Pink Seal Cushion Chair (I have the Hexagon Necklace already). Which one would sell for more mesos? I could also get a Flaming Katana but I don't have Undine's Cloth, so that's out of the picture.
