Those are pretty similar in profile to cherry spacebars.
They are quite different. SP spacebars have sharper front edge.
Those are pretty similar in profile to cherry spacebars. EK spacebar=same profile as SP space bars?
It is my guess, because of the shape and the texture. I think you can send them an email to verify.
Edit: I take out my Moogle kit and compare with the EK's pic and I see that they are different. It is probably not SP spacebar.
