This product meets these three criteria but it has a flaw: being left-handed, I thought a marker that does not clear dry would be a good solution to avoid erasing what I just wrote with the side of my hand. However, these wet erase markers are provided for the illustration or erasable but durable inscriptions. Liquid chalk fits perfectly when allowed to dry a few minutes, but it is not practical when you want to write a lot, and often able to re-clear the square or to rephrase an idea.
I contacted the customer service of Stationery Island, which impressed me with its professionalism and usefulness of advice, telling them about two problems: the first was that the ink is not erased immediately when we spent a damp cloth (it must pass the two cloth or three times), the second was a problem with the flow of the marker. They told me that I had not chosen the right product for my needs, and that if I wanted a marker that has all the same qualities but goes back very easily, I needed to use the markers that s 'wipe dry. They proposed me to make me try their dry markers, and I'll post a review when I have been able to test them :)
In this issue, I therefore conclude that I did not understand the proper use of these markers. They are perfect for pretty "tags" temporary, logos and illustrations (for Christmas or for decorating windows) on smooth surfaces. The colors are vibrant and opaque. The ink really holds very well once it has dried, which makes it ideal for customizing glass glasses before a night out or to make exercise tables to be completed for children or students, for example in a primary class or languages. I can not wait to test in dry version, and probably I will use those to damp dry in some situations!
When the question of the stream, here is the solution: you really shake well before Felt start using (about 20 seconds) and make sure to have correctly "pumped" the ink in the tip . It is not enough that the tip (which is white at first) becomes colorful, definitely it is saturated with ink or foam slightly on the draft you use to pump. If the stream is uneven or the chalk appears "aqueous" or if you are forced to interrupt e-frequently to pump / shake again is that you have not pumped enough or not shaken enough early use.
In conclusion, I recommend this purchase altogether for illustrations and durable inscriptions (but perfectly erasable!), Bright and opaque colors, and comfortable use (fluid writing and fairly neutral odor) on smooth surfaces .
