Best coaster set in this comparison
For coasters and a holder, the LET'S RESIN 18-piece set is the top pick. It is 15 coaster moulds and 3 holder moulds in round, square and octagon, at £17.99, with 4.5 from 2,399 reviews. Fifty UK reviews were read. Beginners report an easy release with resin they already owned. The seller states about 3.4 inches and says a torch or heat gun is not recommended. The cover image shows a pattern the plain cavities do not cast. Skip it if you wanted that pattern. A minority call the silicone thin. Resin is not in the box. EPODA at £13.99 is the cheaper holder set: four round, four square and two holders, 4.4 from 385. Fourteen UK reviews include a mould that was not flat, dents and scratches, and circles that stuck and tore. The listing disagrees on 8, 9 and 10 pieces. Save the £4 only if you will inspect every cavity before you pour. Skip both if you need pendants or a bottle of resin.
Best first kit
If you have never poured and you want a named frame, HeyClear at £24.99 is the kit to open: a frame mould, 1 litre, glitter, gloves, cups, a mat and a manual. It is 4.6 from 860, but only nine UK texts were in the file. One buyer said the resin took three days to set. One parcel missed the mat. LET'S RESIN's 500 ml kit at £23.99 is 4.5 from 3,504, with 50 UK texts and clear casts reported. The four moulds are unnamed and often called small. Instructions are a repeated complaint, sometimes safety notes only, and the age range is Adult. ZEROMX at £23.79 names a vase, pyramid, sphere and cube, plus 600 ml called 1:1 and an LED base, at 4.5 from 179. One experienced user said the resin would not set and spoiled other moulds. Battery, mains, voltage and any UK plug are absent. Skip every kit if the resin is already on your shelf.
Best value when the job is narrow
Under £9 wins only when the shape is the one you will pour. The ZMD sheet at £7.59 is the best value for deep rounds: six cavities, about 4 inches, 0.8 inch and 165 ml, 4.7 from 30 reviews. About 10 cm by 1.75 cm is large for a normal coaster. The listing says casting resin, not coating resin. Buy it for a thick round. Opopark at £7.99 is three word moulds, 4.5 from 697, if you accept thin strokes and check the letters are not reversed. One UK reviewer said they face the opposite way. TPTGIAR at £5.99 is 16 pendant moulds and 20 chains, 4.4 from five ratings, and no resin. It is cheap only for keyrings. simarro at £5.39 and ZHUOmengyun at £8.99 state a shallow tray and a 1.8 cm heart, and they have no star line.
What best cannot mean
Best here means the listing that matches a stated job, with a review sample large enough to show the usual failure. It does not mean a laboratory winner, a food-safe award, or a mould that will take a hot pan. Food-grade on the simarro silicone is not a food-contact proof for cured resin. A live amazon.co.uk page can move. The £17.99 and 2,399 figures are the file on 19 October 2026. If the moulds are still 15 plus 3 holders, the pick stands at a new price. If resin or the shapes have changed, treat it as a different product.
Common questions
Which mould set has the most UK reviews for coasters?
The LET'S RESIN 18-piece set, at 4.5 from 2,399, with 15 coaster moulds and 3 holders. EPODA is 4.4 from 385. ZMD is 4.7 from 30, a higher average on a much smaller sample. Use the larger count for a usual coaster, and the 30-review sheet only for the deeper cavity.
What is the cheapest set that still matches a real job?
TPTGIAR at £5.99 matches jewellery if you already have resin. simarro at £5.39 matches a shallow tray, with no reviews in the file. ZMD at £7.59 matches a deep round and has 30 ratings. A pendant mould is not a discount coaster.
Which kit is the safer first box?
HeyClear if you want a named frame and 1 litre, knowing only nine UK texts were read. LET'S RESIN's 500 ml kit if you want 3,504 ratings and you accept small, unnamed moulds. LET'S RESIN's age line says Adult. Skip ZEROMX when you need a known plug for the light.
Who should skip the word moulds?
Skip Opopark if the cast must read the same way as the product photo, or if you need thick walls. Reviewers describe thin strokes and a snap when the resin was pulled early. At £7.99 and 4.5 from 697 it is still a fair word set if you check the cavity and wait for a full cure.
Who should skip a kit?
Skip it when you already own a compatible epoxy. You would pay about £24 for liquid and for moulds that may be small or unnamed. Also skip ZEROMX if a failed cure would wreck other moulds, because one reviewer reported a resin that did not set.
Is 4.7 from 30 ratings better than 4.5 from 2,399?
Not as a general winner. ZMD's 4.7 from 30 is too small to outrank a coaster set with 2,399 reviews at 4.5. Compare ratings only when both moulds do the same job. A deep round and a coaster set do not.
