Reading in a comment: "Small price for 250 tubes" jignore the price of this type of article in France, but in Belgium this'll be back to 110 the 250 tubes box! or there is an error on Amazon, or France really more a tax home!
The tubes of the OCB brand are perfect, I've used them with an electric tube machine. They are easy to use, the tube is not consumed too quickly, I recommend it! Small price for 250 tubes.
