It came as a package from Amazon with an Amazon receipt. I bought it from here so I thought that was kind of weird. Also the receipt was for the pens, but they were priced at $18.99. I got them for $28.
I suggest finding his account on Amazon and buying them through there.
The pens themselves aren't bad. I kept mine in the plastic container they came in and they started to break so don't keep them in original packaging
