Fix your crystals to your base

Crystals are not secured to any of the CRYST bases. 

Most people feel drawn to hold their crystals or carry them with them. Securing them to a base obviously won't allow you to do this, and it also makes it difficult to dust/clean the base. 

If however, you have purchased a set and you would prefer them to be secured, you can secure them by using a double-sided adhesive tape. 

There are a number of different brands that offer double-sided adhesive tape. Choose an adhesive tape that is clear and circular so that it won't affect the look of the crystals.
