Hi Joy, yes it is. Yes the paints are available to order separately. 625 is blue, 616 is black and 601 is white. Regards Jenny

Hi, yes you can use them on canvas if you wish or any kind of fabric. They are spirit-based paints so will dry quicker. They can be applied direct from the ball-point or squeeze some out onto a palette and use with a brush. If brush-painting you may need to dilute them with the Tip Cleaner/Thinners not water. The Complete Guide also shows you everything you need to know. Regards Jenny

Hi Lisa, thanks for your question. Hobbytex Vogart paint is spirit-based paint, which makes it virtually instant drying and permanent. It won't fade or wash out of the fabric. You need to use a thinners to dilute if painting with a brush and palette. Rgds Jenny

Hi Anthea, thanks for your question. The plastic tube Guards are sold separately and not really required for these smaller tubes but they do fit if you want to order some at $1 each Guard. These smaller tubes do come complete with a ball-point tip and a plastic Dome (lid) to protect the tip on each tube. Plus the same spirit-based paint inside. Regards Jenny

Hi Kathy, The paint in the tube is spirit-based and therefore lasts a very long time. Some customers have had their paints for over 20 years and so all you need to do is replace the ball-point tip. Simply unscrew the old tip with the Stylus/Tip Wrench (Item 1616) or a pair of pliers and screw in a new one by hand, tightening with the Tip Wrench. Always have some paper down as the paint may come out especially if they have been squeezed as the pressure will have built up inside the tube. Replacement tips are available in packs of 3, 10 (Item 1670), and 25 (Item 1651 $35/pack). Click on the accessories heading on the home page to see the tips. Regards Jenny
