StoneFyr Storage — Frequently Asked Questions
What grading companies are CoinConnex cases compatible with?
CoinConnex™ cases fit standard graded coin slabs from NGC, PCGS, CAC, and ANACS.
What are your products made from?
StoneFyr products are 3D-printed in PLA and PETG depending on the product. PETG is an engineering-grade thermoplastic with higher strength, better heat resistance, and greater chemical stability.
Can I get a custom color?
We stock standard colors. Custom-color requests are available subject to filament availability and order size, and may add to lead time.
Are the cases stackable?
Yes — CoinConnex™ cases stack securely. The modular design lets you build out your storage system incrementally as your collection grows.
What's the difference between CoinConnex and SlabGrid?
CoinConnex™ is enclosed storage with sliding lids for protection during storage and transport. SlabGrid™ is open display trays for presentation and organization with easier access.
