Most of our products (with the exception of density marker beads) are sold as a dry powder prepackaged by weight, volume, or count.

Unfortunately, we cannot accept returns on custom made microspheres or on opened/resealed packages.

If you are interested in re-selling our products in your country, you are welcome to do so. However, we do not offer distributor agreements, discounts, custom labeling or packaging.

Are all 2000 SKUs of microspheres, nanospheres, and precision spherical particles in stock?

The website is updated daily with the latest inventory information. However, it is possible that multiple orders for the same product might come in on the same day and a specific product might sell out. This happens infrequently. In that case we will email you and offer a recommendation for a substitute product.
