Hi Endie,
Here’s a photo of a #20 stock unit on the left and a #18 on the right. Please remember that judging color from a photo is not accurate due to lighting and monitor settings--it’s just a ‘ball park’ idea of the color. The #20 is more blonde and the #18 is a very light brown. And for newbies the wave on all stock units is body wave or one step up from straight. Don’t get concerned about the wave in the photo--it looks very curly--since that curl comes out once the unit is combed. This is how the units look right out of the bag and with the netting still on. We have all solid color stock units on hand and can ship immediately.
Regards,
John
