Computer made/mounted on velcro. 4.0 inches or 100mm.

Shipping in the USA by US post Office first class mail at $4.50 WITH tracking. I will combine shipping for multiple patches. 

Overseas shipping is $3.50 for 2 patches depending upon weight. Each additional patch will be $1.00. Anything over $50, I would highly recommend registered mail which is $18.00 plus postage.
