We use a very high heat process to produce a permanent image on a metal insert which is adhered with a super strong 3M adhesive to our hard plastic or silicone rubber cases designed especially for this unique printing process. All cases are available for the iphone 4/4s or iphone 5. (the iphone 4 case is our default if a choice is not marked during checkout) Available in either black or white (WHITE MUST BE SPECIFIED IN NOTES TO SELLER DURING CHECKOUT- otherwise the black case is sent as the default case) AVAILABLE in hard plastic or silicone rubber. (SILICONE RUBBER IS OUR DEFAULT CASE IF HARD PLASTIC IS NOT MARKED DURING CHECKOUT). We STRONGLY recommend the silicone rubber case as it is much more durable and less prone to chipping or cracking than the hard plastic case. It is also much easier to take on and off the cell phone. Our cases are slim fitting and cover the back and sides of the cell phone. They provide protection against scratches, dust and mild trauma. RETURNS: If you are not satisfied with our products for any reason, simply return within 2 weeks of receipt for a full refund. HARD CASES MAY NOT BE RETURNED AFTER 2 WEEKS-WE STRONGLY RECOMMEND THE SILICONE RUBBER CASE AS IT IS MUCH MORE DURABLE.
