Customer Questions & Answers

  • Question: What is the DirectGlow Invisible Blue UV Ink Pen used for?

    Answer: The DirectGlow Invisible Blue UV Ink Pen is primarily designed for writing secret messages or creating invisible markings that only become visible under UV light. This makes it ideal for security applications such as marking items for identification, creating hidden messages, or for use in educational settings like science experiments where UV reactions are demonstrated.
  • Question: How does the UV ink become visible?

    Answer: The ink in the DirectGlow pen is formulated to be invisible under normal light conditions but will fluoresce when exposed to ultraviolet light. This reaction allows users to reveal hidden messages or markings, making it perfect for discreet writing, security marking, or even arts and crafts where you want to create surprise elements in the artwork when viewed under UV light.
  • Question: Is the ink safe for skin and other materials?

    Answer: Yes, the ink used in the DirectGlow Invisible Blue UV Ink Pen is non-toxic and safe for use on skin, making it suitable for face painting or temporary tattoos during events. However, it's advisable to test on a small area of other materials such as fabrics or surfaces first to ensure there is no adverse reaction or staining.
  • Question: Can I use this pen on various surfaces?

    Answer: Absolutely! The DirectGlow Invisible Blue UV Ink Pen can be used on a variety of surfaces including paper, cardboard, plastic, and even wood. This versatility allows you to create secret messages in books, mark personal belongings, or add elements to crafts and DIY projects, enhancing creativity and security.
  • Question: What is the drying time of the ink?

    Answer: The ink of the DirectGlow pen dries quickly, typically within a couple of minutes depending on the surface and environmental conditions. This fast-drying feature makes it convenient for users to write and reveal messages without worrying about smudging, making it a great choice for both artistic endeavors and practical applications.
  • Question: Is the pen refillable?

    Answer: Currently, the DirectGlow Invisible Blue UV Ink Pen is not designed to be refillable. This means that once the ink is used up, you will need to purchase a new pen. However, considering its affordable dual pack offering, users can stock up and ensure they have plenty on hand for their projects or security needs.
  • Question: How do I safely store the UV ink pen?

    Answer: To ensure longevity and optimal performance, store the DirectGlow Invisible Blue UV Ink Pen in a cool, dry place, away from direct sunlight. Keeping the cap tightly closed when not in use also helps prevent the ink from drying out, ensuring that your pen remains ready for whenever you need to create secret messages or markings.
  • Question: Can children use this product?

    Answer: Yes, the DirectGlow Invisible Blue UV Ink Pen is suitable for children as it contains non-toxic ink. However, adult supervision is recommended to ensure the ink is used appropriately, especially when creating crafts or during educational activities. This makes it a fun and safe option for kids' parties, art projects, or science experiments.
  • Question: What type of UV light should I use to reveal the ink?

    Answer: To effectively reveal the ink from the DirectGlow pen, a standard UV blacklight is recommended. These can be found in various forms such as handheld flashlights or bulbs. Using an appropriate UV light will ensure that the invisible ink fluoresces brightly, allowing you to see your hidden messages or markings clearly.
  • Question: Where can I buy DirectGlow 2 Pack Invisible Blue UV Blacklight Reactive Ink Pen Marker Security Secret Message?

    Answer: You can purchase the DirectGlow 2 Pack Invisible Blue UV Blacklight Reactive Ink Pen from Ubuy. Ubuy offers a reliable shopping platform where you can find high-quality products with convenient online ordering options.
