I can only see PayPal option for payment

Select PayPal at checkout (no PayPal account needed) and you will have the option to add your debit/credit card information.

I personally wrap the painting in wrapping paper firstly, then bubble wrap it. A third layer of fine plastic wrap is used to secure the painting and the previous wraps. Next, the painting is carefully placed in a corrugated box and then again plastic wrapped to ensure maximum protection. The shipping company then may or may not use an additional packing.

I do take commissions and can work on something if you have in mind. Feel free to reach out to me!
