DD doesn't get along so well with the Berol ones as she tends to wear them sideways, IYKWIM. There's another sort she likes, but they cost about 4 quid each and don't last that long . . . Any recommendations?
(I've suggested a cartridge pen, but apparently they're not popular with teachers owing to a few explosive ink accidents in class!) She's in the demented-spider league for handwriting, so biros not ideal.
