Which is better for Christmas ornaments?

The Artrylin set. Its 3D spheres with pre-cut hanging holes are made to hang on a tree. The Valtira makes flat 1.77-inch discs that work as small ornaments but look thinner.

Which is better for coasters and trays?

The Valtira. Nine shallow 0.6 cm cavities produce flat rounds suited to coasters, cup mats and trinket trays, and you get nine at a time instead of four.

Both are silicone and should survive many pours if you release pieces gently and avoid sharp tools. The Valtira has no buyer rating; the Artrylin sits at 3.8 out of 5 from 4 ratings, which is too few to judge longevity.

Is the Artrylin set worth it over the Valtira?

Worth it if you want 3D ornaments about 3 inches wide. If you mainly make flat pieces in quantity, the Valtira's nine cavities do more per pour. Check both current prices on this page.

Can I use the same resin in both?

Yes. Both take epoxy and UV resin. The Artrylin also lists polyester resin. Deeper sphere cavities trap more bubbles, so pour slowly and use a heat tool.

How big are the finished pieces?

Valtira pieces are 1.77 inch across and 0.6 cm deep. Artrylin spheres are roughly 3 inches across, so they use noticeably more resin each.
