🧪 Resin, vinyl and PVC: what art toys are made of
Vinyl and PVC are the same family and cover almost every mass-produced figure. Resin is cast in small runs, heavier, sharper in detail, and far more fragile. The material explains most of the price gap.

The three you will meet
| Material | Feel | Breaks how |
|---|---|---|
| Soft vinyl | Light, slightly hollow, gives under a squeeze | Dents and creases, rarely shatters |
| PVC or ABS | Firmer, solid, most blind box figures | Snaps at thin parts |
| Resin | Noticeably heavy, cold, glass-smooth | Chips and shatters if dropped |
A blind box figure is nearly always PVC or ABS. Resin turns up in artist runs, small-batch designer pieces, and anything described as hand-cast or limited to a low number.
Why resin costs what it does
Resin is poured into silicone moulds that wear out after a few dozen casts, and each piece is cleaned and painted by hand. That is the whole explanation for the price: it is a short run of hand-finished objects rather than an injection-moulded one. It also means small variations between copies are normal rather than defects.
Living with them
- •Keep everything out of direct sun. Vinyl yellows and warps, and pigment fades on all three.
- •Never leave a figure in a hot car. Vinyl softens enough to deform under its own weight.
- •Dust with a soft dry brush. Solvent cleaners lift paint, especially on resin.
- •Resin needs a shelf it cannot be knocked off. A single fall usually ends it.
- •Soft vinyl that has dented can often be relaxed back with warm, not hot, water.
A quick shop-floor test: pick it up. If it is heavier than it looks, it is resin. That one signal separates the two price tiers more reliably than any label.
