Hiddur means "Adornment." Our Tefillin are "adorned" with extra beautifications and stringencies.

At Tefillin Beit El, we pay close attention to each and every letter and crownlet, in order to ensure that our Tefillin is unparalleled in quality. The best way to explain how we make "Tefillin Mehudarot" - Tefillin with Hiddurim - is by showing how we write a sample letter. We have chosen the letter Gimmel

		The Parts of the Gimmel: 1. The Head 2. The Right Leg 3. The Left Leg
		The Gimmel's Hiddur Adornments: 1. The head 2. The right leg 3. The left leg 4. The crown 5. Corners at the extremities of the head 6. The right leg is connected to the middle of the head 7. The right leg is tilted inwards 8. The end of the right leg is narrow 9. The right leg extends a little bit below the left leg 10. A thick line joins the left leg to the right leg 11. The left leg is tilted slightly upwards

Thus is created not only a Kosher letter gimmel, but a Mehudar letter gimmel.
