This is a lot of vintage photographic chemical products. While most kits appear sealed, the seller has not opened or verified contents for usability, chemical stability, or completeness.

Due to age, these chemicals may have degraded, crystallized, separated, or otherwise changed from their original state and may not be suitable for use.

Buyer is responsible for reviewing all photos carefully and asking any questions prior to purchase. If additional photos are needed, please request them before buying.

Sold strictly as-is for parts, display, collection, or experimental use. No returns for condition, usability, chemical performance, or completeness.

Buyer should conduct own research regarding proper use, compatibility, and expected performance of vintage photographic chemicals prior to purchasing.

Thank you
