Pros
- Mirror-gloss interiors skip polishing
- Includes the matching holder mold
- Thick walls hold shape over many pours
Cons
- Round shape only in this set
- Holder mold needs a large resin batch
Don't buy this if…
- Skip it if you scratch molds with metal tools; one gouge in the gloss face shows on every future coaster.

- Fine detail reproduction
- Efficient use of leftover resin
Cons
- Small cavities trap bubbles easily
- Thin sheets tear if flexed hard
Don't buy this if…

Ranked #3 based on expert reviews, user sentiment, and value analysis.
Pros
- Large-format tray in one pour
- Rigid base resists bowing mid-cure
- Glossy face needs no post-finishing
Cons
- Needs 500g-plus of resin per tray
- Storage footprint is large
Don't buy this if…

Ranked #4 based on expert reviews, user sentiment, and value analysis.
Pros
- Handles deep-pour casting heat
- Classic shapes for preservation pieces
- Seam lines are minimal and easy to sand
Cons
- Sphere molds need careful fill through small ports
- Only geometric shapes
Don't buy this if…
- Don't pour fast-cure coating resin in these; the exotherm in a 3-inch mass can smoke and crack.

Ranked #5 based on expert reviews, user sentiment, and value analysis.
Pros
- Complete keychain hardware included
- Letters read correctly when demolded
- High margin for craft-fair sellers
Cons
- Letter cavities are shallow and fragile
- Included hardware is basic plated metal
Don't buy this if…

Ranked #6 based on expert reviews, user sentiment, and value analysis.
Pros
- Makes genuinely functional decor
- Thick silicone keeps corners square
- Pairs well with dried-flower inclusions
Cons
- Consumes a lot of resin per pair
- Long full-cure before weight-bearing use
Don't buy this if…

Ranked #7 based on expert reviews, user sentiment, and value analysis.
Pros
- Full domino set from one mold
- Crisp pip and edge detail
- Three game types in one kit
Cons
- 28 cavities take patience to fill cleanly
- Dominoes need flat post-cure storage to avoid warp
Don't buy this if…

Pros
- Forgiving freeform edges for beginners
- Designed for the popular ocean-pour style
- Inexpensive multi-pack

Don't buy this if…
