Creating your Custom String Subscription could not be any easier. Visit the shop and view our string selection like you would on any other online shop. When you find the strings you would like to have in your subscription, just select a Billing & Delivery Period of Every Month or Every Other Month and the number of packs of strings you would like to receive. Then just press the Add to My Subscription button. This will add this subscription item to your cart. If you want to select another type of strings, just repeat this process for the other strings. You can add as many different strings to your Custom String Subscription as you want. When you have all of your subscription items in your cart just proceed to the checkout. You can pay with a credit card or PayPal. That’s it. It couldn’t be easier.
