1、Are the glass marbles dyed? Will the color fade when soaked in water?

They are made using a through-body glass coloring process where the color permeates the entire bead, rather than being a surface spray-paint finish. They will not fade, become cloudy, or delaminate, even with prolonged water immersion, outdoor sun exposure, washing, or friction.

2、 Do the products have burrs or sharp edges? Are they safe for children to play with?

All edges are precision-ground by machine to be rounded and smooth; there are no sharp corners. They are non-toxic and odorless, making them safe for children to play with and for home display.

3、Can they be placed directly into fish tanks or ponds?

Absolutely. The material is stable, releases no harmful substances, and does not pollute the water. They are waterproof, corrosion-resistant, and excellent decorative materials for aquascaping; simply wash them before placing them in the tank.

4、Will the glass marbles have air bubbles or impurities?

These are high-clarity glass marbles produced under strict quality control, resulting in very few air bubbles or impurities. Due to the nature of the manufacturing process, the occasional tiny air bubble is a normal characteristic and does not affect their decorative use.
