1. Item Details:
Rosin Flux Pen
Due to popular demand, we are making our Rosin flux pens that are part of our solar cells kit available for purchase individually for DIY solar panel makers.
Rosin flux is a chemical cleaning agent that facilitates soldering, and it's in a very user friendly pen format for easy application onto our solar cells's bus bars and tabbing wires. Always apply flux on the bus bars or wires first before soldering, and the bonding job will be easy. It works great with our solar cells.
For precision application of rosin flux, in a convenient microtip pen format. RA type flux.
Superior fluxing ability
After soldering, the rosin residue is non-corrosive, non-conducting, moisture resistant, and fungus resistant

How to use the flux pen:
The tip of the flux pen is dry when new. There is a seal inside the flux that you need to break before the flux liquid will moist the tip. To break the seal, point the flux pen upward, and depress the tip into the shaft of the pen. The tip will spring back to its original position. Wait for a few minutes then the tip will be moister and ready for use.
Shipping is $4.80 for domestic order. However, if you purchase this item with our other items exceppt accessories, then shipping would be free! We ship the packages via US Postal Service priority mail, and we buy USPS delivery confirmation for all of the shipments at our own expenses. For orders that are 250 and above, we buy 'Signature Required' so that you sign of the package as well, unless you tell us not to - we will still buy delivery confirmation for you. This will make sure that you receive the cells. Delivery confirmation will give us a tracking number from which you can see online that delivery has been confirmed, but no signature is required. 'Signature Required' features says exactly that, and it's different from 'Delivery Confirmation' by the Post Office.
For international orders, we are not responsible for your import duties, customs charges or other VAT's. And we don't know what the charges will be for each country. Do not get upset with us because your government thinks that you should pay extra. In actuality we would prefer to do business all within the United States, but we have some good customers from other countries so that's why we keep our international shipping program. We reserve the right to terminate our international shipping program at any time. Please check with your country's customs office prior to purchasing to determine what these additional costs will be.
3. Product Returns
We used to have a more strict sounding return policy, but when we looked at the numbers, returns are really so rare we now say that you can return the cells within 7 days broken or not for a complete refund with us paying the return shipping. We keep selling our products at such attractive value and we are the original manufacturer that makes a lot of new products that we are going to sell direct to our customers so cheaply it would be stupid to burn the bridge. So far our customers are overwhelmingly happy with the great value and support that we provide.
