If your kids / sibblings/ grandkids are anything like my daughters you will mysteriously have less tops than pens.
Here's your chance to even those numbers.
Print out a new pen top to keep those Crayola Felt Tip Pens from drying out.
This has similar airways to the original pen tops, but please be careful with this top and remember the insight of BS-EN71. blah blah blah no substitute for adequate supervision. Or something like that. It's been a few years since I looked at the toy Standards. I should remember that better.
Anyway, print the snesible way up.
See the X-Sections for details.
This fits onto the Crayola Felt Tip Pen I modelled the other day:
