Black Biro Pens Pack of 100

Product Information

The best way to remove biro from fabric is to use a stain removal product that is fast-acting and powerful enough to thoroughly clean the fabric without being too aggressive on the fibres which could cause long term damage. It is generally believed that because of a ballpoint pen's reliance on gravity to coat the ball with ink, most cannot be used to write upside-down. However, the reason most ballpoint pens on the Earth do not work when writing upside-down is because the Earth's gravity pulls the ink inside the pen away from the tip of the pen, resulting in a bad writing experience. However, in space, the regular ballpoint pens can work upside-down because the microgravity in space is not strong enough to pull the ink away from the tip of the pen and capillary action prevails. [39] The reliability of the regular ballpoint pen was tested in space [40] by Pedro Duque, an ESA astronaut in 2003.

Then you can apply liquid laundry detergents to that area if possible. Rub the detergent or cleaning solution into the stain or biro mark with a clean cloth and that’s it.

Some ballpoint pens use a hybrid ink formulation whose viscosity is lower than that of standard ballpoint ink, but greater than rollerball ink. [30] The ink dries faster than a gel pen to prevent smearing when writing. These pens are better suited for left-handed persons. Examples are the Uni-ball Jetstream and Pilot Acroball ranges. [32] These pens are also labelled "extra smooth", as they offer a smoother writing experience compared to normal ballpoint pens. This barrier also reduces friction caused as you use the leather. Dirt and grime, combined with daily use slowly wear away the coatings on leather. The Protection Cream takes away this friction and so will help prolong the life of your leather.
