Quick verdict
This AliExpress filament bundle looks like a budget-first shortlist rather than a confident quality pick. The listing points to 1.75mm PLA, an unbranded NONE brand, and a very low current price of £3.99-£4.09, which is attractive if you mainly want a cheap multicolour pack. The trade-off is that owner-review evidence is weak, so it is better treated as a compare-first option than an automatic buy.

What the product page clearly says
The listing title is doing most of the work here: 30 colours, 1.75mm PLA, 16.4 feet or 5m per colour, and 492 feet or 150m total. Two tracked options are shown and both are in stock, which gives a small amount of choice, but not a wide range of variants. Because the item is unbranded and the live review detail is thin, the key checks are compatibility, colour mix and final UK delivered price.
What the wider comparison tells us
Against 765 comparable 3D printer filament listings, this sits close to the median peer price of £4.59, so it is not unusually expensive or unusually cheap for the category. The main attraction is the stated bundle size at a low entry price, not a strong reputation signal. Similar title patterns also exist in price-tracking data, which supports the view that this is a common low-cost filament format rather than a standout branded product. That makes it useful as a compare-first budget bundle, especially if you value the headline 150m total more than brand familiarity.
Buyer trade-offs to weigh before ordering
The biggest question is whether the 1.75mm PLA claim matches your 3D pen or printer, because a low headline price is only good value if the filament fits your device. Colour accuracy is the next trade-off: the title says random colour, so shoppers who need a specific shade or exact mix should be cautious. The final delivered price matters as much as the £3.99 starting price, since shipping can change the value picture quickly. With little owner-review evidence, this is a practical budget gamble rather than a low-risk purchase.
Price and value benchmark
At £3.99-£4.09, this bundle sits close to the comparable-product median of £4.59, so the pricing is competitive without being extreme. The fact that two variants are tracked is a small plus, but the bigger value question is whether the extra colour count and stated 150m total are genuinely useful for your project. If you are comparing with other AliExpress filament bundles, weigh the delivered price, colour selection and review backing together instead of chasing the lowest headline number.
How it compares with nearby alternatives
Compared with more clearly specified or better-known filament options, this one leans heavily on the title claim rather than on brand identity. The 1.75mm PLA spec is the main technical point to verify, because compatibility matters more than the 30-colour headline if you are buying for a specific 3D pen or printer. If your priority is consistency, stronger product support or clearer colour selection, a better-reviewed alternative may be safer even if it costs a little more. If you only need a low-cost multicolour bundle for basic use, this listing stays in the conversation.
How to read the review evidence
For this AliExpress listing at £3.99-£4.09, there is no meaningful owner-review count shown, so the visible rating details should not be treated as proof of quality. The seller is also listing it as NONE brand, which makes the weak review picture even more important to notice. External reputation context can help you compare cheap filament broadly, but it does not verify this exact 30-colour, 1.75mm PLA bundle. If you want a product with stronger confidence behind it, look for a filament listing with clearer buyer feedback and a more established brand identity.
Who it suits
This bundle suits budget-minded shoppers who want a multicolour PLA option and are comfortable checking the fine print before ordering. It is most appealing if you are buying for simple 3D pen projects, school activities or low-stakes craft use where a low entry price matters more than brand identity. The 30-colour, 150m total headline also makes it attractive for anyone wanting lots of small colour segments rather than one large spool in a single shade.
Who should avoid it
Skip this if you need strong evidence of consistent filament quality, dependable manufacturer support or predictable colour matching. Buyers who want a trusted brand, detailed buyer feedback or a specific non-random colour selection should look elsewhere, especially because this listing is NONE brand and the current price is only £3.99-£4.09. If your project depends on accurate, repeatable output, the unbranded status and weak owner-review evidence make this a higher-uncertainty choice than a more established alternative.
What to verify before you checkout
Confirm that the live AliExpress page still shows the same 1.75mm PLA specification, the current in-stock status and the full UK delivered price. It is also worth checking whether the colour mix is truly random or limited to the displayed option, because the title and the tracked options do not promise a custom palette. If your 3D pen or printer is picky, make compatibility the first check rather than focusing on the headline colour count.
Value judgement
The value case here comes from the low starting price and the large stated bundle size, not from brand reputation or review strength. If shipping stays modest and the 1.75mm PLA claim matches your device, the pack could be a sensible cheap way to stock up on multicolour filament. If delivery pushes the total cost up, or if you want better certainty on colour and consistency, it becomes easier to justify paying more for a better-reviewed alternative.

Questions about this product
Is this 1.75mm PLA filament compatible with my 3D pen or printer?
It may be, but you should verify the live AliExpress specification against your device before buying. The title states 1.75mm PLA, yet compatibility still depends on your pen or printer’s exact filament requirement and whether it accepts this format reliably.
Is the low price still good value once UK delivery is added?
Only if the final delivered price stays close to the current £3.99-£4.09 listing price. Because shipping can change the value quickly, check the checkout total on AliExpress and compare it with better-reviewed filament bundles before deciding.
How reliable is the listing if there are few or no visible owner reviews?
Not very reliable as a quality signal. With no meaningful review count shown, the listing should be treated as a budget compare-first option, so verify compatibility, delivery and colour details rather than assuming the title alone proves good filament.
Are the 30 colours supplied exactly as shown or is the mix random?
The title says random colour, so do not assume you will receive a specific shade set. If colour choice matters for your project, check the live listing carefully and confirm whether the bundle is truly random or whether only one option is available.
Should I choose this unbranded bundle or a better-reviewed alternative?
Choose this only if price and bundle size matter more than brand confidence and review support. If you need steadier expectations on consistency, colour accuracy or support, a better-reviewed alternative is the safer comparison, even at a slightly higher price.
