Wegwerfabroller with cooler role

Here the name is correct rather than the product image: The band is really grass green and not neon.
Post-its I use for years very much for everything and there is really a lot of good post-it products.
The idea of ​​the role is actually awesome. One can thus seal something that is to be opened again (goes with Tesa not) or use them for the actual purpose, something labeling it or leave notes.
Compared with cleats they are converted to the price per square meter is almost three times as expensive (depends on the offer, I have the prices of today and Post-it taken for comparison 670-5). But these ones are wider, they can be individually cut and glue them to the entire area. These are three positive characteristics.
Why is it still only 3 stars?
I would never buy this product because it is a disposable product. The dispenser does not open or refill. You have to buy the dispenser new roles ever. Here siollte Post-it think again for the environment. In addition, the product would be cheaper of course, when the dispenser would be reusable.
Negative is also that of the dispenser, the paper not just tear off. For Father labels it's okay if the edge is not straight. But the longer-term as the product photos I just want to have edges. Since only helps the scissors and then turn the dispenser is useless.
The following must be done, so I rate the article (or its successor) with 5 stars:
1. The dispenser must be reusable, it must give refills.
2. The dispenser requires a sharp cutting edge, so that the post-its are cut cleanly.
