Your jewellery order is inclusive of the first print kit.
Your prints do not need to be perfect at all.
Sometimes extra fingerprints appear, fingers get pressed twice leaving 7 fingers on one hand print or prints get smeared!
As long as Impressions to Keep can see where the real print is, photo shop will do the rest and your prints will be fine.
However, …… very occasionally it does go wrong and you may wish to try again.
Please check with me before purchasing a second kit, they are not redeemable against the cost of your jewellery and you may not need to buy another. But if you do they are just £5.
