These markers stand out with their unique dual-color effect, which automatically creates beautiful outlines, adding a special touch to any artwork. They perform well on various surfaces, including paper, wood, glass, and more, making them versatile for numerous crafts and DIY projects. However, they work best on thick, light-colored paper for the most vibrant outlines. The markers are easy to use - just shake, press, and draw, which is great for both kids and adults.

One drawback could be their durability; being made of plastic, they might not withstand rough handling by very young children. Nevertheless, their build quality seems solid for regular use.

A unique feature of these markers is the dual-color effect, which adds an extra dimension to artwork, especially on different surfaces like light-colored paper, black paper, and smooth surfaces such as glass or metal. This makes them suitable for a wide range of projects from Christmas cards to scrapbooking and more. Durability seems satisfactory, with the markers designed to work best on thicker paper and requiring immediate recapping to maintain their quality. However, children under 3 should use them under supervision due to small parts.

Ease of use is highlighted with simple instructions on mixing the ink and priming the tip. Despite these advantages, the markers need to be stored horizontally and properly capped to avoid drying out, which may be a bit cumbersome for younger kids. Additionally, while the markers are widely versatile, their effectiveness can vary on different materials, potentially needing some trial and error. These markers are ideal for kids and teens who enjoy arts and crafts, offering both creativity and fun.

The ZSCM 21 Colors Shimmer Glitter Markers are designed especially for teens and craft enthusiasts who want bright, eye-catching double-line effects with a metallic shimmer. One of the biggest strengths is the wide color variety—21 vibrant shades including black, silver, pink, and blue—giving you plenty of options for creative projects. The markers produce a unique double-line or 'super squiggle' effect, which suits trendy crafts, greeting cards, posters, and more. The tip size is medium, which balances precision and smooth ink flow for both writing and coloring tasks.

These markers work well on many surfaces like paper, glass, wood, and plastic, making them versatile for different types of art projects. The ink dries quickly and is non-toxic and odorless, which is a plus for safe use by teens and kids under supervision. On the downside, the instructions suggest you need to shake the pens and pump the tips to get the ink flowing, which might be a little tricky for younger users at first. Also, the markers perform best on heavier paper (80gsm or above) to avoid ink bleed-through, so standard thin paper may show some strike-through. Durability seems decent when stored properly with caps on and kept horizontal, though some users might find the ink runs out faster with heavy use.

These shimmer markers provide a fun and colorful way to add metallic double-line designs to art projects, making them especially appealing for tweens and teens looking for a trendy, glittery touch.
