Review: Without this extender my ink dries out quicker than I ... - Without this extender my ink dries out quicker than I can put my print on a canvas. It’s an affordable alternative than just buying oil based ink, especially since I got all my ink from gifts
Review: Tubes Blow Up From End - More than half of the tubes that I have ordered from Speedball have broken open at the end while I am using the ink. Ink is wasted and it causes a mess. The packaging is awful.

### ⭐⭐ Tubes Blow Up From End
*by E***Z on June 2, 2024*

More than half of the tubes that I have ordered from Speedball have broken open at the end while I am using the ink. Ink is wasted and it causes a mess. The packaging is awful.

### ⭐⭐⭐⭐⭐ Works great
*by C***G on December 22, 2017*

Works well, does seem to change the color when mixing with multiple inks.
