This is a Matfer piping bag. It's thick and large. It's disposable, but if you wash and care for it, you can use it several times. It measures 59cm vertically and 28cm horizontally, measured at the longest point of the triangle. I will send 10 brand new, unused bags via anonymous post. The box is not included. I may end the listing suddenly. I will discount the difference in shipping costs for combined purchases. Please understand that I do not accept price negotiations.
