since she did this one as a one off it's home made iron on and needs to be taken care of quite carefully. for her mass produced ones it's all hi quality print.
she was thinking of adding this model into her next batch but maybe with some modifications, like differences between the three valves and such. she sells hers 30$CAD locally, so put that into GBP and add the shipping which would be close to 5-7 GBP i guess.
