Let customers speak for us
from 4318 reviewsThis makes a awesome birthday present!!
The Reflex Hammer is a solid choice for testing reflexes. Its latex-free construction and bold red color make it both safe and easy to locate. While relatively basic, it gets the job done for reflex testing.
Received item fairly quickly and item was as described. Will do business again!

The look awesome
I use paint I mix from pigment I get on Culture Hustle USA and then sprinkle these on the pictures to make them really, REALY bright under a uv light. Very fun.
Our family has been a big fan of Glo Pals for a few years and were excited to see that our local science shop was carrying them. They make bath time so much fun!
