Glow-in-the-dark colour pens can be used to add glow-in-the-dark highlights to art and craft projects. Create your own glow-in-the-dark features on drawings, stickers, posters and books with these easy to use glow-in-the-dark pens by The Original Glowstars Company. Adds that special touch to party and Halloween decorations! In the pack, you will receive three 10ml glow in the dark pens. Gently squeeze the pen as you write or draw pictures for your bedroom walls, charge them up in the light and then watch them glow at bedtime. The glow-in-the-dark pens give an embossed, colour finish when applied. Your creations should be left to dry overnight. We recommend that you protect surfaces and wear some old clothing whilst using the pens, as the colour does not wash out of clothing. Any spillages should be wiped up straight away with a damp cloth. 6+
