They are painted w/ special glasspaint and then heatset for durability,but as with fine glassware I would still recommend handwashing.
The stems are each painted in a different color and that makes each one easy to identify.
The stems are also painted w/ a marblized design,a gold swirl design on the glass part and the base is a leopard design.
These glasses are both fun and sophisticated.
My preferred method of payment is Paypal although I will accept checks and will ship USPS as soon as payment is cleared and in the bank.
