I had ordered in 2011 and sent back, because on the product photo blue roles were mapped. The return and refund of the purchase price went smoothly.
The picture has changed. Therefore, I have improved my rating from three to four stars.
Strangely, I find, however, that the internal diameter in the photo with 32mm is specified in the text and with 25mm. The roles that have been delivered to me, in any case fit perfectly on my 25mm rods.
