The idea for these products arose from clothing at first but soon came to cover as many product types as on all the other net stores that I have. My first thought was: I could now design exactly the kind of climbing t-shirt as I'd really like, something I'd gladly wear in those activities. From there, the ideas just kept flooding and I think the best ones are still to come.
Later on, there will be previews of some of the products below and through their product pages you'll access the print-on-demand stores directly. What can you find there? For example clothing, but also phone cases, pillows and cushions, blankets, bed sheets, mugs... The list is long!
There are numerous base color options on these print-on-demand stores. Ordering is easy and, according to my experience, delivery takes from a few days to two weeks. All the transactions go through the store and it also handles any possible returns or reclamations. It is something that I'm not even able to help with.
Also note, that these stores have almost always different kinds of sales (e.g., all t-shirts –20%). Therefore, if you like some design it pays off to check each store's pricing on the design at that moment. To take t-shirt as example, it certainly isn't exactly the same make and the graphics on it may be of a bit different size—but you'll easily find out the differences.
