From the update:
Impact! has reached the Stretch Goal needed for them to also create a D22 as part of their KickStarter to create spherical D14s and D18s in 8 colors. Multiple package options available with the dice starting around $2 each.
KickStarter ends on Monday August 27th and currently everyone pledging $16 or more gets one free die (and the project is quickly reaching the Stretch Goal to give everyone pledging $17 or more a 2nd free die)
